any chance Scott Brown comes out with a statement that says "tee hee, just kidding! I'm not really going to run fro Senate in somebody else's state." ?
No chance at all. This is a good thing for republicans, as Brown is consistently polling better against Shaheen than the other republican candidates are (Former NH Sen. Robert Smith, Former NH State Sen. Jim Rubens, and Perennial Candidate Andy Martin).
Polling better than people nobody's heard of isn't a huge distinction.
The people of New Hampshire never heard of Bob Smith when they elected him to the Senate?
He left the party to run for President in 2000 then moved to Florida to run for Senate there and is back for the first time in 12 years, so lots of people don't remember him. And even amongst those who do, he is, for the most part, persona non grata
Does anyone actually think Smith has a chance? He's run a terrible campaign, especially for a former senator, and has hardly raised his name recognition. The only thing he could possibly have going for him is the "Scott Brown is a Carpetbagger" sentiment.
