President Obama’s big rally tonight turned out to be just like his first, opening salvo of the 2012 campaign: a half-empty arena in Ohio. According to RealClearPolitics’ Scott Conroy, there were “empty seats scattered around the upper-level of Nationwide Arena … Four years ago, after all, Obama was easily filling venues larger than that …” The event even featured Bruce Springsteen and Jay-Z, and Obama still couldn’t fill it out.
