Joe Lieberman wants to be president. It’s as plain as the nose on my face. His first chance was in 2000, as Al Gore’s running mate. Though they didn’t win, it did position him favorably for a shot at the 2004 nomination. Jo-mentum ran that year, but was never taken seriously, never rising from low digits in the polls. He was probably insulted.
In 2008, Joe probably saw a road to the White House through John McCain. He probably thought he would be the running mate, and would land, at last, the vice presidency, and later the presidency should McCain kick off early or decide not to run after four years.
The parties don’t disagree on Iraq, or Afghanistan, or the so-called War on Terror. There was no substance to Joe Lieberman supporting McCain beyond his own personal ambition.
He’s not that hard to figure out.
