President Truman's old adage that there are no friends in politics has been put on vivid display this election season.  Even in CampClinton, long time allegiances don't seem to hold water anymore. And, just as we did four years ago, we had the Democratic presidential nominee (John Kerry, for those of you who've blocked it out) diss his former running mate (my guy, John Edwards) and endorse someone else -- the junior senator from Illinois.

Which, of course, brings to mind my personal fav, Sen. Joe Lieberman (I-CT), who turned his back on Democrats (again) when he endorsed Sen. John McCain (R-AZ) for president. Never mind that Independent Joe caucuses with the Democrats or that it's our majority which provides him with the committee chairmanship (aka, bully pulpit) that he loves so much. It seems sadly appropriate that Joe gave the Dems the cold shoulder from the frozen tundra of New Hampshire.

Joe's really a piece of work when you think about it. Let's not forget that good ol' Joe lent his weighty support to McCain instead of home state Sen. Chris Dodd (D-CT), as is traditional -- yeah, remember, Joe, when Dodd was the only senator who endorsed your wannabe, also-ran candidacy back in 2004, when you had your own delusions of grandeur about the Oval Office having your name on it?

Now, I know Dodd endorsed Ned LaMont, Joe, after he beat you in Connecticut's Democratic primary -- as did the rest of the Democratic party. You lost the party's nomination fair and square and for good reason, Joe. Dodd was just playing by the rules. But paybacks are hell, huh? I guess you learned about that when your former running mate Al Gore endorsed Gov. Howard Dean over your two-faced self four years ago. Bet that stung.

What's next, Joe?  A McCain-Lieberman ticket? Hmmm.... well, you share bylines, write legislation in tandem, why not crisscross the country together in a vain attempt to show your mutual obsession with a failed war policy really ain't so bad after all?

While you say you have no ambitions to be VP (sure, Joe, 'cause your politics over the past few years haven't demonstrated an ounce of personal ambition), Sen. McCain credits good ol' Joe's endorsement with helping him out in New Hampshire, putting the wheels back on the Straight Talk Express. So, he owes you, right Joe?

Especially if you keep honing your skills at playing the gratuitous hitman role against the Dem's presumptive nominee, Barack Obama. The lastest bit about Obama being Hamas' candidate of choice was inspired -- and you even said it with a straight face. Way to memorize those talking points, Joe. I mean, hey, if you can show the Maverick up front that you're willing to be his lap, um, I mean, attack dog, he'll have to move you to the top of his Veep list, right?

Well, don't bet on it, Joe...there are no friends in politics, as you've amply demonstrated. Don't count on being rewarded for this latest sucker punch, Joe. I wasn't shocked by your endorsement/defection to Team McCain. And I wasn't shocked when you lumped your former party's frontrunner in with militant extremists. In fact, you're becoming depressingly consistent. It's no wonder you endorsed John McCain -- none of the other Democratic candidates asked for your support, and who could blame them? 

I just wish Majority Leader Harry Reid would get a clue, and boot you out of the Democratic caucus once and for all.  Becasue for you, Joe, I really hope that what goes around really does come back 'round again -- and slaps you upside the head. At the very least, Reid should take your chairmanship away and give it to a senator who will actually vote Blue in November, as he recently hinted.

But the sad fact is, for now, we still need your sorry ass to keep the Dems in power. But that won't be the case next year, Joe. The Democrats are looking good to take back some prime Senate seats, and hopefully that means your double agent days are numbered. It couldn't happen to a nicer guy.
