Senate right now is 51-49. If Lieberman held out, it's 50-50, with Cheney holding the tie-breaker. We're back to 2001 all over again.
Yes, and Joe Lieberman, personally, holds the balance in his sweaty little hands, allowing him to feel like the very important person he believes himself to be. If he flipped, Cheney would hold that power. Joe would be nothing more than the winner of the vital Green Room primary. And this is off-topic anyway. The man is endorsing a Republican for president after saying quote clearly during the election that he will not. He is doing everything he can to elect him. He will speak at the RNC next summer. (Just watch.)
If you were the leader of the Republican caucus and a White House Republican liaison to Congress, would you want Lieberman to switch parties? The obvious thing is that it could give the Republicans working control for the next year. But that would put the Vice-President Dick Cheney more in the spotlight, and is that a good thing for the party. Also, would this help the Republicans in 2008, a year where they have a lot of retirements and a lot of seats to defend. And they would get a Senator who has voted against them for domestic programs. How could they justify their conservative beliefs if they accept Lieberman into their caucus?
That assumes that there are any principles left in modern conservatism after it followed Fredo over the cliff.
The Republican principles of looking out for their corporate interests and trying to squeeze working stiffs? Those principles are as solid as ever.
There's a pretty good chance that if the little feller loses, Joe Lieberman's career is finished. Thank goodness. This country didn't need another Benedict Arnold.
