Mitt Romney: 'Corporations are people'

Republican presidential hopeful Mitt Romney has maintained his position as the frontrunner after facing seven other candidates in a TV debate earlier this week.

But the former governor had a tough day in Iowa recently, where he is campaigning ahead of Saturday's Iowa Straw Poll.

At a state fair, he was heckled and yelled at as he maintained that he does not favour higher taxes on the corporations because "corporations are people, too".

Mitt Romney hopes to win the Republican nomination to face President Barack Obama in the November 2012 general election.
