I actually have grown to like Obama a lot more than I thought I would (McCain voter in 2008). Partly due to my economic views shifting from a Chicago-style view to a more balanced, nuanced view that recognizes that monetary policy is crucial during economic downturns but also partly because the Republican party seems to be shifting to the right socially for some reason. I don't know if I can bring myself to vote Republican as long as they keep pandering to the anti-intellectual forces within their party. I love Obama's foreign policy and I, along with many Americans, took issue with the GOP trying to unfairly capitalize on the Benghazi tragedy, facts-be-damned.
As for people just voting for the incumbent, surely that was part of it as well. People always prefer the devil they know to what was an especially big question mark with Mitt Romney and his ever-evolving "plans."
On a side note it looks like our teams might be facing off in the Orange Bowl.
Actually this pretty much sums up my thoughts on Obama and the republicans too.
