We'll have our monthly 2012 poll out tomorrow but here's an interesting data point in advance of them.
Among the people who voted for Barack Obama in 2008 but don't approve of his job performance:
-Mitt Romney's favorability is 32/31 (+1)
-Newt Gingrich's is 32/40 (-8)
-Mike Huckabee's is 20/39 (-19)
-Sarah Palin's is 33/63 (-30)
Palin continues to be the most well liked of the leading 2012 contenders with GOP voters. Whether she's the one who can appeal to disaffected Obama voters is another story. And Gingrich and Huckabee don't appear to be in a great position to get the support of those folks either. Romney's numbers are the strongest but the data still suggests Republicans might be best off with someone outside the current top tier of candidates.
