I’m not a Democrat, but I usually end up voting for Democratic candidates, simply to vote against their Republican opponents, since we have no viable third party in the United States. Why? Sometimes it’s because I disagree with particular Republicans on actual political issues — issues involving personal liberty, most commonly.
Often, however, my primary reason for opposing Republican candidates is more fundamental: I’m horrified by the idea of stupid people running the government, and a growing subset of prominent Republicans are shockingly deficient in intelligence, as revealed by numerous dumb things they say, or, in this case, tweet. Examples of this sort of Republican include George W. Bush, Sarah Palin, Rick Perry, Michele Bachmann — and now this one, Tom Cotton, currently running for the U.S. Senate in Arkansas, where I live.
What is it about the Republican Party that attracts politicians with two-digit IQs, and why does this trend seem to be getting steadily worse?
