What if, instead of giving up his Senate seat in an attempt to run for President in 2004 and ending up as Kerry's V.P., John Edwards runs for reelection in North Carolina. Who do you think would John Kerry's running mate be? Gephardt? Daschle?
One more thing, with Edwards running for reelection, does he win and would this butterfly away Rielle Hunter and allow him to run without problems in 2008? And what would an Edwards Presidency in 2008 be like? I assume that there would be a great focus on poverty and in some areas, he would be more liberal and active than Obama.
Would a Democrat do all that well in 2008 following a Kerry presidency? It's well-known that my fellow Americans have a two-week memory and blame whoever is the current President for everything.
Seriously, whoever is elected President in 2004 will get a lot of flack for the economy, regardless of how fair the accusations are. They will associate Edwards with "failed" Democratic policies. 2004 is too late to prevent the economic collapse, as the bad loans and complicated derivatives were already coming into place.
As for everyone's favorite Breck Girl John Edwards, he won't meet Rielle Hunter in this timeline, since apparently they met in 2006. Considering he's the type to cheat on his cancer-stricken wife, he'll be certain to do SOMETHING to alienate the public. I imagine half the fun of writing American politics timelines is coming up with gaffes and October Surprises.
However, Elizabeth Edwards might die of cancer (first diagnosed in late 2004) before Edwards commits adultery, meaning his reputation hobbles along a bit longer. This is really the only hope alternate Edwards has, in a very perverse sort of way.
His large house and preference for expensive haircuts may allow the Republicans to attack him as a "limousine liberal" too if sex scandals don't sink his political career. How successful these political ads will be is up to the timeline writer.
