In Michael’s article [ed: removed dead link] on the Specter cross-over, regular reader c3 asks:
Just for the sake of discussion. How is this different than what Joe Leiberman did?
I think what’s different between Specter and Lieberman is that, as far as I know, Lieberman hasn’t flipped-flopped between saying one thing and then doing another, while Specter has. Yes, Lieberman himself flirted with the idea of becoming a Republican once upon a time, and was John McCain’s first pick for running mate last year, but he hadn’t spent months telling us that it would never happen and then suddenly did it. I actually found Lieberman to be quite transparent with his thought process. He went public with the fact he was considering it.
Specter is a different animal altogether.
