threads like this make me think I'm on the wrong message board. I can name more people from The Office than I can sitting US senators.
To some it is like being an extreme sports fan.
If you are going to the length of endorsing senate candidates from 10 different states in your signature then its probably a given you will be up on their names and faces.
By a rough off the top of my head
Both (11): MI (not yet, Kid Rock), TN, KY, NJ, VT, SC, AZ, HI, IL, ME, CA
One (18): NM, CT, OR, MN, MO, MA, PA, WV, FL, TX, UT, WI, IN, AL, GA, AK, NE, LA
So 29 of 50 states.
