Economist/YouGov Poll (48% Obama, 43% Romney)
September 26
The President continues to lead his Republicans challenger in the presidential race as he has since the conventions. That lead has remained steady: in the latest Economist/YouGov Poll, 48% of registered voters favor Democratic President Barack Obama, 43% support Mitt Romney, the Republican.
The gap in enthusiasm between Romney and Obama supporters, which was particularly evident throughout July and August, has diminished markedly as of late. Although slightly more Romney supporters (45%) describe themselves as "extremely enthusiastic" about casting a ballot than Obama voters (41%) do, Obama voters make up the gap once those who are "very enthusiastic" are included.
Whereas 86% of Obama voters expect the President will definitely or probably be re-elected, only 53% of Romney voters think their candidate will win.
The race continues to be about the incumbent. More than half of those voting for Mitt Romney admit they arent really voting for Mitt Romney. 56% of Romney voters say they are mainly voting against the President. By contrast, 81% of Obama supporters are voting for their choice.
