A truly terrible day, IMO.
I would suggest the non-politically inclined and politically apathetic were actually less inclined to vote for Obama and instead just note period. I base this on personal experience and voter turnout. I'd be inclined to agree Obama was a bad president, so long as it was recognised that I think think Bush was worse and Romney would have been worse. (I love the choice between bad and worse. It makes me want to run out and vote for... well.. neither.)
It's popular for a lot of young people in the U.S. to support Obama (even ones that possess very limited political knowledge) because of his embrace of the idyllic values of "hope" and "change", although this was less pronounced in 2012 than in 2008. Romney was absolutely pummeled among youth. And this is also due, to be fair, to the increased social tolerance of the millennial generation, many of whom grew up with George W. Bush in the White House and have thus developed a very negative paradigm of the Republican Party that they are likely to carry for much of their lives (or until another Republican is elected President and turns out better than Bush).
