He won't hurt anybody, because he has almost no support left. In 2004, he got 0.82% in Connecticut; in 2008, he got 1.16%. He will do nothing in 2010, even if he does run.
That being said, I think he'd break 5% easily. Maybe even 10-15% if he's lucky. He has the name recognition down.
Name recognition is not always a good thing. I would assume his favorable numbers are something like 9/48. And most of the 10% or so who like him will not vote for him. See Patrick Buchanan in 2000.
