Excellent article exploring the very real possibility of if Leiberman was president:
What if Al Gore had won the 2000 presidential election but died in office? Would President Joe Lieberman have been worse than George W. Bush? His recent actions suggest that he could have descended even lower in his illogical and immoral responses to the tragedy of 9/11. Although now an independent, Lieberman provides a cautionary tale for folks who talk of backing "any Democrat" who can win.
At a time when even President Bush has recognized the need for negotiations with Iran in order to stabilize Iraq, where disciples of Tehran's ayatollahs have risen to power, thanks to the U.S. occupation he fervently supports, Lieberman urges war with Iran. "I think we've got to be prepared to take aggressive military action against the Iranians to stop them from killing Americans in Iraq," he told CBS on Sunday, "and to me, that would include a strike over the border into Iran."

Having fallen for the Iranian plot to gain control over Iraq, Lieberman now seeks to undo the damage by invading Iran. He is apparently unaware of public warnings that key Shiite leaders in Iraq would take up arms again in support of their co-religionists across the border. Indeed, the Iranian arms being smuggled into Iraq that Lieberman complains about are going to the Shiite militias dominating America's surrogate government in Baghdad.
Bush seems to grasp this reality, which is why the United States is now negotiating with the Iranian ambassador in Baghdad, leaving Lieberman to play the role of a hawkish critic of an administration he apparently feels has lost its enthusiasm for yet another disastrous invasion. This is a man whom leading Democrats, including Bill Clinton, supported in his primary campaign against an intelligent Democrat who sought to end the Iraq nightmare.
