Jon Huntsman is the only GOP candidate who simply stated that he believes that scientists probably better understand climate change and evolution well enough to be trusted on the topic. Last night, he got 1% of the vote at the Iowa caucus.
This, as much as anything, seems to capture what is wrong with Republican politics. The gap between what makes for smart policy and smart policy is wide and seemingly growing. Whether it is ignoring climate change or getting excited about starting a war with Iran, any candidate wanting to win over Republican voters seemingly has to thumb his nose at what makes sense in terms of policy.
