PPP shows a dramatically different picture of this race than recent Rasmussen polls have portrayed, with Paul clearly the weaker general election candidate for Republicans. Paul's favorability rating among all voters has shifted from 26-23 in December to 28-35 now -- likely the effect of Grayson's attacks finding more resonance among the wider general election audience than the GOP primary electorate.
The problem, however, is that the leading Democratic candidate, Dan Mongiardo, is the least popular person in this four-man field with a favorable rating of just 24-36. Even with Mongiardo at the con, though, Paul's candidacy should at least keep this one interesting.
Meanwhile, Rand Paul received a bit of help today from Jim DeMint, who broke his neutrality to endorse Paul to try to balance out the many DC Republicans who have lined up behind Grayson.
