Eh, this is to be expected with his position on the embargo. In theory this'll be counteracted by bigger margins in the corridor.
This reminds me of a quote from fantasyland (I think it was lief)
In 2010, we saw record gains by Republicans, but Republicans really didn't gain numbers, Democrats lost numbers. Scott ran in that wave, and these last four years he has been signing bills and legislation that make old conservatives happy, and they always vote. Scott's even airing ads about his accomplishments to Crists failures, the one that stuck out to me thus far is the student loan ad, where even I was impressed.
I'm afraid that Democrats aren't enthusiastic about Crist, and many of those who vote "enthusiastic" only do so because he's a Democrat now.
In fantasyland I was ahead in the polls by a substantial margin, but I didn't turn out my base, and Crist will do the same thing here. He isn't a good candidate, and you can argue all you want, but the only reason Democrats are supporting him is because of the possibility of winning, and not much else.
And I'm afraid we're throwing away this seat with him.
