PPP's monthly national survey looking at how Barack Obama fares against some potential 2012 opponents finds the same basic two conclusions it did in April and May:
-Obama would get reelected by a margin greater than or equal to what he won against John McCain if he had to stand before the voters today
-Mike Huckabee is the most popular and strongest against Obama among the quartet of GOP hopefuls we've been testing, which includes Newt Gingrich, Sarah Palin, and Mitt Romney.
Obama holds a seven point lead over Huckabee, equal to his margin last fall, an eight point advantage over Gingrich and Romney, and a 12 point edge on Palin.
Huckabee is viewed favorably by 43% of voters in the country, with 35% looking at him unfavorably. Romney's numbers are 41/36. Gingrich and Palin both have negative ratings at 35/46 and 43/49 respectively.
Palin's reviews are basically the same as last month, indicating that her public spat with David Letterman has neither created sympathy for her among former detractors or caused her to lose any popularity.
Obama's approval rating is 52%, the low end of the 52-55% range PPP has found for him nationally over the last four months. His usual high ratings among Democrats and low ones among Republicans continues, but he is slightly negative with independents this time around at 46/49.
