John McCain can have Lieberman

I'm sure picking him to run with you will go over so well with your base. After all, this was a man so doctrinal Democrat that he was chosen to be run as Vice President in 2000.

In fact, this is mentioned in the article:

“Conservatives would be pissed as hell – I think you would have a revolt, but sometimes John does what John wants to do,” the McCain adviser said.

Yes, yes, they would - it hasn't been so long ago that he was Sen. Juan McCain.
