Most of the people I know here in TX are now anti free traitor as well. This may have some good legs in 2008.
"How do you think that will play in New Hampshire?"
I don't think it will hurt him one bit in NH, or even New York or California.
Free Trade and job outsourcing in even liberal, latte drinking states is not really very popular, while it is hugely unpopular in the rust belt where a big chunk of the swing states will be.
I know lots of liberals, independents, and Republicans at my office, and I have never met one person whose number 1 issue is demanding massive/unlimited free trade with other countries.
Now strategically, I doubt Allen would have to turn into Pitchfork Pat Buchanan to be competetive in the Rust belt. He just needs to move to the center on freetrade, like promising to renogotiate NAFTA, or put a moratorium for a few years on any major Free Trade deals.
Moving to the center on Trade, rather than the Paleo/right or Union/Left may work well in Michigan against Hillary "My Husband Invented NAFTA" Clinton.
