Even tho he was a Democrat, Alvin Greene is exhibit number 1 in any argument that people pay less attention to Senate primaries than they should.
Hm, I think Greene was born to win that primary. He would have had my vote.
Still, unwinnable races would tend to be low profile...I wouldn't judge New York Republicans by whatever unknown sacrificial lamb they throw at Chuckie. My examples were using races that were contested.
Edit: Greene also won that primary due to his name, nothing else. Would seem to help my argument that name familiarity is the winner in a race that is low profile.
