When faced with an overwhelming primary threat from within his own party, Specter immediately sold them out and lept into the somewhat welcoming arms of the opposition party. Unlike Connecticut, Pennsylvania has a "sore loser" law that makes it impossible for the loser of a primary to then seek to win the election as a petitioning candidate.
So he admitted that he switched parties, not out of some miraculous change of ideology, but for simple self-preservation. Never underestimate the shameless ambition of an incumbent threatened by a strong primary challenge!
At least Specter was honest about his naked desire to hang onto his office, whereas Joe Lieberman embraced the GOP after repeatedly swearing during the general election that nobody wanted to see a Democrat win the 2008 election more than he. Then he immediately stabbed the Democratic Party in the back and enthusiastically supported McCain in repayment for the GOP's funding of his second chance at keeping his seat.
So Specter became a Democrat. But while doing so, he stated that he wouldn't be a "loyal Democrat"; this raised a few eyebrows.
Then the very first thing Specter did as a newly Democratic senator was to vote AGAINST the Democratic budget. More eyebrows elevated.
And then just yesterday, Specter stated in the NY Times that, "There's still time for the Minnesota courts to do justice and declare Norm Coleman the winner."
You've GOT to be kidding me!
OK, now I'm convinced he's just fucking with us.
Well done, Senator, you got us! You're quite the joker, that's for sure. I had no idea you were such a scamp, Arlen.
However, on the off-chance you're NOT joking...
...well, there's a very good Democrat in PA who's rumored to be making noises about a possible primary against the long-time-until-last-week Republican:
Congressman Joe Sestak (PA-7)
We may be seeing a lot more of him next year.
