First who is Joe Lieberman?

In the context of the Senate he was a nobody until he runs to a microphone to rebuke the President of his own party.

Suddenly, he's in the limelight. Suddenly, he's on the map.

In fact, he's so much "someone" that he becomes the Vice Presidential candidate!

But that doesn't work out... so he runs for President.

But that doesn't work out... so he tries to retain his senate seat in the Democratic primary.

But that doesn't work out... so he reverses directions, abandoning his party loyalty, adopting all sorts of Republican positions in order to stay in power as an Independent.

But now he's utterly marginalized, so he provides cover for the Presidential nominee of the OTHER party... while privately lobbying to become second-in command.

OK, so.. who is John McCain?

He was a "maverick" for years, climbing the ranks of the Republican party, with the plan to run for the office of the President of the United States.

But that doesn't work out... so he tries to stay relevant by running to the floor of the Senate every chance he can to "rebuke" the President of his own party on Iraq.

But that doesn't really work out... because his party hates him, marginalizing him.

So, in the next election cycle he provides cover for the Presidential nominee for the other party... while simultaneously privately lobbying to be second-in-command.

But that doesn't work out... so he reverses directions, abandoning his previous branding to adopt all sorts of Republican positions in his second attempt at the seat of power.

So, in the end, I can't honestly tell you who either of of these men ACTUALLY is... other than two people who don't seem to care in what way they get their hands on the Executive branch of the American government, only that they do.

Republican... Democrat... Independent... President... Vice President... doesn't fucking matter... just so as long as its THEM.
