The people of Wisconsin will proudly support a Wisconsin Republican. That's how 28 year old Paul Ryan stomped his opponent 57-43 in a D+2 open seat in 1998.
Will people stop with this BS about just having someone from a state guarantees it will go of your party. It didn't work in 2004, it didn't work in 1996, it didn't work in 1988, 1972, or 1968. You'll get a bump of 2 points, if any at all. The Washington Post says you probably wont even get a bump.
Actually, given that North Carolina did not give President George W Bush an increased share of the vote in 2004, compared to 2000, it certainly worked at doing something.
The Wisconsin GOP figured out in 2010/2011/2012 what it could not do in 2000/2004's close elections; namely, generate the max number of votes in Waukesha. They will use those lessons.
