Scott Walker knows how to beat unions -- what else can he do?

Throughout his interview with BuzzFeed, Walker repeatedly declined to comment on issues that veered too far outside his wheelhouse. For example, the co-author on his book is Marc Thiessen, the former George W. Bush speechwriter Washington Post columnist. They were introduced through Walker’s agent and “hit it off” immediately, eventually spending several hours every Sunday night on Skype, with the governor leafing through old calendars and dictating his story to the writer. When it came time to send the book to press, Walker insisted on putting Thiessen’s name on the cover beneath his own, breaking with a long-held tradition in politics of well-paid ghostwriters staying firmly behind the scenes. …

But when it came to the national security issues that have defined Thiessen’s career — he has been a full-throated champion of Bush-era interrogation methods, and the president’s post-9/11 policies in general — Walker was unwilling to engage.

Asked whether he thought Guantanamo Bay should be shut down, Walker said, “To me, that’s one of those were before I give opinions on things I like to weigh the facts, and not being elected to federal office I’m probably not privy enough right now to have firm opinions on that.” And quizzed on the ethicality of water-boarding, Walker demurred again: “I don’t spend enough time or have a knowledge base to comment.”
