Arlen Specter - new clothes, same old tired ideas

I have to admit I was at first heartened to hear of Arlen Specter's defection from the Republican party and his new affiliation as a Democrat. Then I watched him vote. What I interpreted is that he changed parties solely to win the Senate seat in PA when it comes up for re-election. He claimed to be more in line with the Democrat's agenda but so far I'm not seeing it.
To vote against the changes in the bankruptcy law was a big give away to me. He is just a Republican in Democrat clothing and I think it's time he retired. We already have one Joe Lieberman. We don't need another.
