Poll: 1 in 5 voters less likely to vote for Mitt Romney because of his wealth

A new Gallup poll shows 20 percent of registered US voters, mostly Democrats and independents, say Republican presidential candidate Mitt Romney's wealth makes them less likely to vote for him.

CNN found most voters, some 75 percent, said the fact that Romney is worth more than $200 million made no difference to how they will vote.

Gallup found most of the 37% of Democratic voters who said Romney's wealth is a negative were already unlikely to vote for him. Gallup's latest demographic analysis shows that 89% of Democratic registered voters prefer President Barack Obama.

More important for Romney are the 19 percent of independents who agreed. Independents are being courted by both candidates in the November election.

On the other hand, about 8 percent of Republicans said Romney's wealth makes them more likely to vote for him.

More from GlobalPost: Mitt Romney at Bain Capital longer than he admitted, report says

In recent weeks, Obama has targeted Romney's wealth and how he earned it as head of Bain Capital. On Thursday the Boston Globe published a story that said Romney's SEC records show he was at Bain longer than he previously admitted. The Obama campaign jumped at the media reports, calling Romney dishonest.

In the meantime, USA TODAY reported Romney has been unapologetic about his wealth.

"I'm not going to apologize for success at home," he said earlier this week. "I went out and began a business, and the business turned out to be far more successful than I ever would have imagined."
