This started as an attempt to annoy a somewhat too Obama-struck Democrat on Facebook, but I think the question is an interesting one to play with at this point:
Imagine that Gore had been given Florida in the 2000 election and was thus elected president. How would subsequent history have been different? Who would be president now? (Would anyone outside of Illinois have heard of Obama?)
I’ll provide my initial thoughts in the comments in order to keep the playing field level.
