Mitt up by 12?

Rush Limbaugh just mentioned a Datamar poll that shows Mitt Romney up by 12 in Florida. 

This poll is not included in the RealClearPolitics average, although previous Datamar polls have been. I've never heard of Datamar, and I have no idea how legit the poll is. I'm curious, though, why no one else is talking about this. 

Mitt's InTrade numbers are below McCain's again, but not by much: 50.5 for McCain, 45.5 for Romney. Remember, in Michigan, Mitt's InTrade numbers were in the 30s up until the day of the primary. Florida is close enough that those numbers aren't especially predictive in the race between McCain and Romney. The one thing they do illustrate, however, is that Giuliani is toast. He's trading at 2.6.
