Who seems to have said that in 2010 when he opted not to challenge Russ Feingold for the Senate seat that Ron Johnson went on to win. But 2 years later, when Herb Kohl decided he'd sat in his seat long enough, Tommy decided to run or saunter over what was an empty seat. It should have been really easy, especially with the Democrats putting up the most left of the liberal Democrats in Congress. Well, it wasn't that easy.
ADDED: Here's Tammy Baldwin's victory speech. Congratulations. I remember her as a student in my class!
