Well, I'm one of those who isn't going to say good-bye to Bayh as I think he will be back, but maybe for a run in 2016 (which presumes--and I use that term carefully--Obama wins re-election). He's also betting that the left will leave him alone once he leaves.
In order not to pile on all of the negatives, I will say something positive about his decision: I've often thought we had too many career politicians, and yes, including Teddy Kennedy, as well as John Murtha, who is being buried in PA as I type this post. Both were good patriots, but many times, they weren't able to get the job done.
My point being (and at the risk of sounding almost libertarian) is that campaign finance reform won't happen. The SCOTUS made sure of that. Lobbyists will continue to take up more jobs in DC and our voices cannot be heard above the loud music played on K street. So, what is the alternative? Term limits --3 for the House, 2 for the Senate--in order to get rid of the asinine chairmanships that keep Joe Lieberman in charge when he should have been kicked out of the Democratic Caucus years ago.
Evan Bayh may be a career politician too. But yesterday, he activated a self-imposed term limit. That's a good thing.
