Wisconsin’s Scott Walker, who since 2010 has won more elections as governor than any other Republican in America, has been making noises of late about running for president next year. Yesterday it became clear that the media regard him as a serious candidate, for a reporter asked him an unserious question. As the Associated Press reports (with, oddly, a Madison dateline): “Walker refused to say Wednesday whether he believes in the theory of evolution, dodging that question and several others about foreign policy after delivering a speech about global trade in London.”
The foreign-policy questions are serious ones, and he promised to get to them in due course: “ ‘I don’t think it’s polite to respond on policy in the United States when you’re in a foreign country,’ Walker said when asked about Islamic State. ‘That’s certainly something I’ll answer in the future.’ ”
But the evolution question—with which the AP story leads—is a silly one. To “believe in” a scientific theory is a contradiction in terms: A theory is not a doctrine to be accepted on faith, but a hypothesis to be tested empirically. That said, it’s fair to describe Walker’s answer at the press conference as a dodge: “I’m going to punt on that one,” he said. “That’s a question a politician shouldn’t be involved in one way or the other. So I’m going to leave that up to you.”
