There are many different opinions, but It all comes down to Mitt Romney just wasn't a good candidate. Think about it here, he couldn't beat John McCain in 08 for the nomination and John McCain lost in 08. So, what do Republicans do? They nominate the runner up to John McCain, lol. This isn't football with the saying of "Any given Sunday", no this is politics where everything comes into play. What I think happened was that people who wanted Romney for their president just didn't go vote. They stayed home because they figured there was no way Obama was going to be re-elected. They thought they didn't have to worry about it. All of Obamas lies and coverups from Fast and Furious to Benghazi, unemployment over 8 percent for his entire presidency, $16 trillion in debt and cities filing for bankruptcy and all the other stuff. They didn't need to vote because there was no way US citizens were going to vote this guy back into office. That will never happen again, or at least I hope it don't. Now all these people are kicking themselves and deserve what's coming to them. I know people are trying to figure out what happened, they don't want to admit it was themselves. Just my opinion.
