Meh. Twitter will be largely pro-Obama because Grandma and GrandPa don't Twitter.
This is a very smart observation, but if you're right, it's just going to be yet another structural advantage for the Democrats, party of people who understand social media.
Not so sure about that. Wasn't there just that stat about Romney's tweets getting circulated more than Obama's? Obviously that's a small element, but an interesting one nonetheless. Seems more likely that there just might not be a lot of crossover between political sides on Twitter, so we just don't see what else is going on.
