At the chance to cover an election unlike any other.
The liberal senator from Massachusetts is not hiding her disdain for presumptive GOP nominee Donald Trump.
Six months ago, I made a reckless vow. With Donald Trump dominating in polls, I said I’d eat a column — 18 column inches of toxic newsprint, wood-pulp, ink and all — if Trump won the Republican presidential nomination.
Chris Cilliza wrote in the Washington Post on Monday of the Republicans' electoral map woes.
"If Clinton wins the 19 states (and D.C.) that every Democratic nominee has won from 1992 to 2012, she has 242 electoral votes. Add Florida's 29 and you get 271. Game over," he wrote.
"What you are left with then is an electoral map in which the Democratic nominee begins at a significant advantage over the Republican one."
More anguish from the Anti-Trump camp, including a conservative writer and Libertarian candidate Gary Johnson.
The Sanders campaign released a statement on his win in Indiana:
I want to thank the people of Indiana for the great upset victory that they gave us tonight. This is the 18th state that we have won, and we expect more victories in the weeks to come. The Clinton campaign thinks this campaign is over. They’re wrong. Maybe it’s over for the insiders and the party establishment, but the voters in Indiana had a different idea. The campaign wasn’t over for them. It isn’t over for the voters in West Virginia. It isn’t over for Democrats in Oregon, New Jersey and Kentucky. It isn’t over for voters in California and all the other states with contests still to come. We understand that we have an uphill climb to victory but we have been fighting uphill from the first day of this campaign. We are in this campaign to win and we’re going to fight until the last vote is cast. There is nothing I would like more than to take on and defeat Donald Trump, someone who must never become president of this country. The voters in the remaining contests deserve a chance to compare my record and Hillary Clinton’s record on creating jobs, raising the minimum wage, war and peace, the need for health care for all, breaking up big banks, combating climate change and other critical issues. To help voters make the best-informed choice possible, I hope that Secretary Clinton will agree to a date and place for a debate in California.
The Ohio governor has not dropped out yet, despite the fact that he has no path to the nomination.
That just hours ago, Donald Trump linked Ted Cruz's father to the assassination of John Kennedy.
Donald Trump's speech following his win in Indiana and subsequent Ted Cruz dropout was fairly short and subdued. He praised his rivals and said he wanted to unify the Republican party. He talked about trade deals, as usual, and said he would win with all demographics in the US.
Bernie Sanders has won the Democratic primary in Indiana, denying former Secretary of State Hillary Clinton another win as she inches closer to the Democratic nomination with a strong delegate lead.
Donald Trump, now all but guaranteed to be the Republican party's nominee, is addressing supporters at Trump Tower in New York. He took a slightly conciliatory tone toward Ted Cruz.
Ted Cruz has dropped out of the race. The Republican establishment is deciding its next move after it becomes all but guaranteed that Donald Trump is their party's nominee for president.

The Argentinian broadcasters of the Copa America have decided they have a secret weapon - Donald Trump.
Next month, the best footballers in the Americas, including Argentina's Lionel Messi, will come to the US for the centenary of the competition, the first time it has been held outside South America.
So a TV station in Argentina has cleverly used footage of Republican Donald Trump delivering remarks about immigrants gaining illegal entry into the US to promote the tournament.
That's a wrap on our live coverage of the primaries in Connecticut, Rhode Island, Pennsylvania, Maryland and Delaware. Stay with us throughout the election season for updates.

Anita McNeal tells the BBC at a Sanders rally in West Virginia that she can still see the senator winning the nomination. But then she is asked if she would back Hillary Clinton as nominee...
Trump and Clinton march closer to their respective nominations.
During his victory speech, Donald Trump levelled a bevy of attacks against Hillary Clinton, but his comments about Mrs Clinton's use of the "woman card" garnered most reaction on social media. Mary Pat Christie - the wife of New Jersey Governor and former Republican presidential candidate Chris Christie - grimaced as Mr Trump made the comment.
Five people, including two small girls, were pepper-sprayed by a demonstrator during a Donald Trump rally in California. Pro-Trump demonstrators clashed with opponents in a heated confrontation. They were treated at the scene. The man thought to be the culprit fled the scene, police said.
He calls tonight's wins "maybe the biggest of them all" and touted his wins against the other Republican candidates.
"I am so honoured...this, to me, is our biggest night," he said, exhibiting a calmer tone than he usually uses in victory speeches.
"I consider myself the presumptive nominee," he said, and he urged Cruz and Kasich to drop out.

Hillary Clinton is joyously addressing supporters in Philadelphia and says she hopes she will be back for the Democratic convention in July.
"We believe in the goodness of our people and the greatness of our nation," she said.
She addressed police violence and income inequality and said many people in the US feel left out and left behind.
"We are going to come together," and solve these problems, she said.
"The faith that we can make things better... is at the heart of who we are as a nation," she said. "It's one of many reasons that being American has always been such a blessing, and our campaign is about restoring people's confidence in our ability to solve problems together."
Evoking some Sanders themes, she also mentioned overturning Citizens United and fighting Wall Street power.

Speculating on the identity of presidential running mates is usually a fun parlour game for wags and pundits during the lull between the end of the primary season and the summer political conventions. Not surprisingly, 2016 is turning this process on its head.
Texas Senator Ted Cruz – who trails Donald Trump in the Republican race and has no path to the nomination outside a contested convention - is reportedly already vetting possible vice-presidential candidates, including former presidential rival Carly Fiorina.
The former computing executive endorsed Mr Cruz last month and has been a regular presence on the campaign trail with him. With the Texas senator facing what could be a make-or-break primary in Indiana next week, he could be hoping a vice-president announcement gives him an extra boost of excitement and free press.
There is some precedent for such a move. In 1976 Ronald Reagan, in an underdog bid to unseat incumbent President Gerald Ford, named Pennsylvania Senator Richard Schweiker, a moderate, to be his running mate.
He still lost. But things turned out OK for him four years later.
Speaking to supporters in West Virginia, Mr Sanders called the electoral system "rigged" and voiced his support for independent voters.
Earlier on Tuesday Donald Trump suggested he run as an independent. However, his wife Jane rejected that idea later in the day on CNN.
Ted Cruz has already shifted his focus away from the five north-eastern states voting on Tuesday and is in Indiana, where he is speaking at a basketball gym.
"Tonight this campaign moves back to more favourable terrain," he tells supporters. Outlining policy priorities, he says Donald Trump's views are similar to Democratic front-runner Hillary Clinton.
The BBC's Gary O'Donoghue is at the rally.
Millennials and individuals with post-graduate degrees are mostly liberal, according to new survey results from the Pew Research Center.
Ted Cruz supporter Jessie Rood told the BBC she supports the principle of the two Republican candidates working together to stop Donald Trump, but she is worried it could add to the front-runner's claims of conspiracy against him.
She said: "By advertising what their strategy is, people are going to think even more that the system is rigged to be anti-Trump."
Mr Sanders is polling ahead of Hillary Clinton in Rhode Island 49% to 45%, according to a poll released Monday by Public Policy Polling. However, a poll released by Brown University puts Clinton in the lead 43% to 34%. Rhode Island is the only primary tonight that isn't closed, meaning registered Independents can vote, which could give Mr Sanders a boost.
On the Republican side, Donald Trump is leading at 61%.
Bernie Sanders' wife, Jane, has dismissed advice from Donald Trump that the Democratic challenger should run for president as an independent candidate.
It came after the Republican front-runner tweeted that Mr Sanders had been treated "terribly" by his party.
Mrs Sanders told CNN on Tuesday her husband did not want to "play the role of the spoiler" for the Democrats.
"We cannot afford a Republican in the White House. We cannot afford a Republican appointing Supreme Court justices. So Bernie will not be running as an independent," she said.
Bernie Sanders is due to be giving a speech in Huntington, West Virginia, later and the BBC's Barbara Plett-Usher has been speaking to some of his supporters queuing to attend the rally.
One of them, named Bill, said he was not disheartened by reports Mr Sanders is on course to lose the nomination, and said he should not pull out of the race.
"I'm always for the underdog," he said. "As far as him losing, it depends on your perspective. I think there's a lot of issues he's brought to the forefront that the Democratic Party needs to address... and Bernie has managed to move Hillary further to the left, where she should be."
A court in New York has ruled that a $40m (£27m) civil lawsuit against Donald Trump and his property investment school will go to trial, according to US media. Democratic New York Attorney General Eric Schneiderman filed the lawsuit in 2013 alleging that Trump University, launched by the New York property tycoon in 2005, used deceptive practices and misled students about the support they would get. Mr Trump has denied any wrongdoing.
No date has been set for the trial and it is unclear whether the presidential hopeful will be called to testify. However, in a statement on Tuesday, Mr Schneiderman said the judge had indicated a desire to move quickly, and he believed Mr Trump would be an "essential witness."
The case is one of several against the private investment school. More than 5,000 people allegedly paid over $40m to take its investment courses.
