Instead, the conservative presidential hopeful, the frontrunner according to a recent Iowa poll, decided to take a pass on the query.
"I'm going to punt on that one as well," Walker said, having already politely demurred when asked a number of questions about U.S. foreign policy. "I'm here to talk about trade, not to pontificate about other things."
Much like his beloved Green Bay Packers during their fourth-quarter meltdown in this year's NFC Championship Game, Walker would punt again soon. This time, Walker's office released a statement to the Milwaukee Journal Sentinel, saying, "Both science and my faith dictate my belief that we are created by God. I believe faith and science are compatible, and go hand in hand."
Hardly a decisive kick. He did, however, manage to lay a boot into the traveling press:
The GOP's "London Curse": Walker is the second Republican governor in the past 10 days to trip over his own feet during a visit to football's spiritual home. New Jersey's Chris Christie stumbled last Monday, when he said he believed "parents need to have some measure of choice" in whether or not have their children vaccinated against easily transferable and potentially deadly diseases like measles. (Unlike Walker, Christie would remove foot from mouth in time to quickly walk back his initial comments, tweeting that there was "no question kids should be vaccinated.")
The party's foreign foibles actually go back to Summer 2012, when presidential nominee Mitt Romney, in London to begin a European tour, questioned whether the city was ready to host that summer's Olympics.
"The stories about the private security firm not having enough people, the supposed strike of the immigration and customs officials — that obviously is not something which is encouraging," Romney told NBC News. The locals responded by dubbing him "Mitt the Twit," an appropriate beginning to a gaffe-tastic week.
The kicker: For Republicans even thinking about running for president, steer clear of London, lest you appear, well, unevolved.
