The lede, from Public Policy Polling:
If Barack Obama had to stand for reelection today he'd win by as much as he did last year, if not more.
He leads Mike Huckabee, Mitt Romney, Jeb Bush, and Sarah Palin by anywhere from 7-15 points in hypothetical 2012 contests.
This is excellent news for John McCain.
