A new poll from Mason-Dixon via McClatchy:

More than half of Americans say they wouldn't consider voting for Sen. Hillary Clinton for president if she becomes the Democratic nominee, according to a new national poll made available to McClatchy Newspapers and NBC News.

The poll by Mason-Dixon Polling and Research found that 52 percent of Americans wouldn't consider voting for Clinton, D-N.Y.

This of course doesn't bode well for her success in a general election contest. However, it's worth noting that since she has consistently had the highest name recognition of all the candidates, voters may be relying on old impressions of her and not the latest positioning coming out of her campaign.
