Sen. Jim Webb To Switch Parties?

Sen. Jim Webb (D-VA) is thinking of switching parties, from Dem to GOP.
From Politics Daily: As you may recall, Webb was secretary of Navy under Reagan, but in 2006 ran as a Democrat against then-Sen. George Allen, ultimately defeating him.Kuhn's interview may spark speculation that Webb is laying the groundwork for a future party switch. Webb voted for health care reform, but tells Kuhn:
"I told him this was going to be a disaster," Webb recalls. "The president believed it was all going to work out."Kuhn goes on to note that Webb "identifies himself as a Democrat. But he has few Democratic leaders to identify with."
Policy differences aside, a practical reason Webb might consider changing parties is that in two years he could face either the current Virginia governor or attorney general or possibly a rematch against George Allen. Webb was able to win in 2006, a very tough year for Republicans, after Allen uttered the word "macaca," a pejorative term aimed at a Webb supporter of Indian decent. But for Webb, getting re-elected in 2012 could be tougher.

It would not surprise me if there are some Democrat Senators who switch parties. especially if they are in a tough re-election fight. Look what happened to Arlen Specter of PA. When things get tough, Specter ran like a baby and he got his butt handed to him by the GOP.
But what does this give the GOP? Really, nothing. Allen could very well be defeated in two years, in which the Dem's are going to face another shellacking in the senate. If Allen switches, the GOP gains nothing- the Senate doesn't switch to the GOP.
So, the GOP should say to him- thanks but if you are interested in switching, do it after 2012.
