Sen. Joe Lieberman (Democratic-caucusing, I-CT) hasn't made any secret of his support for John McCain, and now he's toying with the idea of being the political equivalent of his best man, standing up and giving a speech for McCain at the Republican Convention in September. On Fox News Sunday, Lieberman said:
I want to help him. I’m not going to attack Obama. I am going to explain why I, as an independent democrat, support McCain, hoping that I can convince other independents and Democrats to join me in choosing the man who is clearly more ready to be the president America needs today.
It's not the first time that someone left the gate open and a donkey has wandered into the elephant pen. In 2004 Sen. Zell Miller (D-GA) crossed the party line to deliver a fiery keynote speech at the Republican Convention (he was introduced on the floor as "the conscience of the Democratic Party.) It was a dramatic performance, the likes of which I can't conceive Lieberman coming close to repeating (seriously. Go watch it. Wow.) but the symbolism remains as interesting.
If Lieberman speaks in Minneapolis, will the Democrats kick Joe out of their caucus? Should they? Is Lieberman a traitor, or just making a solid independent decision?
