Day in a Nutshell
The Democrats and a non-partisan election watchdog file complaints with US tax and election regulators. They say two non-profit groups that have spent heavily on advertising backing Republican candidates have failed to file appropriate financial disclosures or have violated tax laws forbidding certain non-profit groups from spending on political advertising.
Meanwhile, there is better news for the Democrats as a poll suggests they are generally making ground on Republicans.

"Boehner, you're almost as dark as me" - Republican Leader John Boehner, the aspiring House Speaker who sports a tan the colour of a roast chicken, paraphrasing a remark he said President Barack Obama made to him.

After months of ominous portents for the Democrats, polls are showing the majority party's chances of avoiding a rout in the November election and retaining power are improving. A Washington Post poll shows the Democrats have halved the Republicans' lead on a generic congressional ballot, in which voters are asked who they would back, an unnamed Democrat or an unnamed Republican.
Meanwhile, in California, Democratic candidates for the Senate and governor's office are holding on to their lead over their Republican rivals, a Reuters/Ipsos poll suggested.
