It is scary that people like that got votes. However, you do have to look at it logically. In elections, those were registered voters who got off their butts and went to their polling place. According to my Civics teacher, the average voter was 45-65, so, not younger people. Younger people tend to be more apathetic toward politics, though Obama got younger people to vote, which is nothing short of a miracle. I hope the trend continues.
As for the primaries, those are all Republican voters. Look at their choices. If they vote, they have to vote for one of those yahoos.
It just blows my mind that last election these idiots promised to balance the budget and get rid of 'Obamacare'. The only part of the health care law they're trying to get rid of is access to birth control. Abortions will be next.
