Let's go back in time to 2004, and consider the following scenario.
You get a chance to replay the 2004 US Presidential election, with Bush/Cheney against Kerry/Edwards. In this scenario HOWEVA:
If Kerry/Edwards wins, John Kerry will have a fatal heart attack in 2006, and John Edwards becomes president. He selects Bill Richardson to be his running mate.
In this scenerio, you know everything about John Edwards that we know now. We know that he's a bit of a sociopath, he was having at least one affair (while his wife was dying of cancer), which would blow up during his second term (if he was able to defeat McCain or Romney in 08 or whatever). We also know that Edwards was willing to let basic morality slide in the name of winning, AND that Richardson was enaging in some sketchy behavior as well.
YOU CAN'T VOTE FOR A 3RD PARTY.
Who do you vote for? For all of the crap that Bush did (the Iraq invansion had already happened at this point), is that preferable to Edwards running the show? Would the combined scandals of an Edwards/Richardson ticket ruin Democrats ability to win elections from 2008-to the current? Note that Obama would still be an Illinois Senator in this situation, unless you think that Edwards screws things up so bad from 2006-2008 that he couldn't run for releection...
