If Al Gore got a few more votes in Florida, he would've won the election. So, going off of that, let's say that Gore/Lieberman is elected over Bush/Cheney in 2000. 9/11 still happens anyways, and Gore goes into Afghanistan, as IOTL. The USA PATRIOT Act is passed anyways, and the GOP still makes gains in the 2002 midterms. There is no invasion of Iraq. By 2004, the world is generally similar to OTL, with the lack of an Iraq War, but not a lack of high tensions between the USA and Iraq, being the biggest difference. However, Iraq is still suspected to have or be building "weapons of mass destruction". If John McCain, a close friend and colleague of Vice President Joe Lieberman, is the Republican nominee in 2004, does Lieberman toe the party line and defend Gore's foreign policy, or does he stick to his hawkish guns and speak out in favor of McCain? If the latter, does Gore keep him, or does he replace Lieberman as his running mate?
