President Obama hasn't been able to convince Americans he's doing a better job on the economy, but he has managed to convince some of them that Mitt Romney did bad things at Bain Capital. Like a Wall Street Journal poll showed in late June, a new ABC News/ Washington Post poll shows ads from the Obama campaign and his Super PAC appear to be working, because people who live in swing states -- and therefore are subjected to tons of political ads -- are more likely to see Romney's business career negatively. Americans as a whole are split on Bain: 23 percent see it as a reason to vote against Romney, while 24 percent see it as a reason to vote for him. But in toss-up states, 16 percent say Bain is a reason to support Romney, while 32 percent say it's a reason to oppose him. More people have an opinion on Romney's business record, too. In February, 36 percent said Romney cut jobs while 32 percent said he created them. Now 40 percent say he cut them and 36 percent say he created them.

But so what? Even in swing states, 49 percent say Romney's Bain record isn't a significant issue in their vote, so it doesn't matter, right? Well, something is making people hesitant to say they're definitely voting for Romney. Even though most Americans say the economy is "extremely important issue" in their presidential vote this year, and most disapprove of how President Obama is handling the economy, and more think Mitt Romney would do a better job handling it --- even with all that, Romney is still only tied with Obama, at 47 percent each.
