Paul Krugman: Good Republicans Reject Evolution

I'm a bit late to this party, but the Pew Research Center recently released a new report about changing views on evolution in the United States. The big takeaway was that a plurality of self-identified Republicans now believe that no evolution whatsoever has taken place since the day of creation - let alone that evolution is driven by natural selection.

The move is big: an 11-point decline since 2009. Obviously there isn't any new scientific evidence driving this rejection of Darwin. And Democrats are slightly more likely to believe in evolution now than they were four years ago. So what happened after 2009 that might be changing Republican views?
