Specter is the ultimate loser. Switch parties and push for Obamacare and he still got primaried by the rats a year later.
Why would Lugar expect any different if he switched parties? He won’t win as an independent either. He already lives in D.C. and can be a lobbyist.
In order to run as an independent he would have to actually move back to Indiana!
He was a double switcher. Prior to 1964, he was a Democrat. He violated my axiom that a politician can only switch parties once in a career with the exception of Winston Churchill, and Specter is no Winston Churchill.
