Remember, this thread is about Repubs boycotting GM. I'm just saying the Dems boycott GM too and put it into action. Why pin it on the Repubs? It seems the unions ought to rethink who their friends are in Washington. I worked for a defense plant under the Steelworkers for 16 yrs. The union wholeheartedly supported the Dem party although it was the Dems who wanted to take away our work and the Repubs wanting to keep us in work. UAW does the same thing.
Anyway, don't get me wrong, I love going to Ann Arbor, despite their liberal leanings and whiney bumper stickers, for the same reasons you state, the mom and pop shops and restaraunts. But I would blame all that on the college kid clientelle and the cramped layout of the campus area, not Dem support. You can't exactly put a McDonalds on the corner of Packard and S. Division, but you can take an old house there and put in a Blimpie Burger. Besides AA has it's share of chain stores too, just like the big mean Republican strongholds.
Don't get me started about NAFTA. We all know who started that.
