It's obvious Lieberman's going to jump, and its also clear the Gore has a lot of support if he decides to run. So I'm hereby predicting that Lieberman runs for the GOP primary, sucks up to the right-wing base, kicks John McCain's ass, and wins.
You know they would pick Joe over McCain. The neo-cons love him more than anyone else other than Bush.
And don't pretend you're not at least a little tickled by the potential irony. Presidential candidate vs. former vice presidential candidate. A Lieberman loss would mean an axe to the neck to the very concept of "Joementum" and what it meant to Gore's majority of votes in 2000.
