Howard Fineman
I forgot to mention that Dirksen, like Obama, was bored to death by the Senate - he died in office.
Yes, I think the candidate for 1955Democrat is Everett Dirksen, who was elected to serve eight successive terms in the Congress. But he was, unfortunately, a job-hopper like Obama too: he then ran for and was elected to the Senate in 1950 for a mere four straight terms. Too bad he's not on 1955Democrat's ballot.
If you feel he is moving too fast for you then don't vote for him. Concentrate on the ones that you like. I'm sure there is a candidate for you.
