Well, it had to happen eventually: after years of competing for the most frantic, emphatic, and redundant support for building a wall along our border with Mexico, a Republican presidential candidate has broken the mold by calling for security measure along our much longer border with Canada (per Bloomberg Politics‘ John McCormick):

Wisconsin Governor Scott Walker said in an interview broadcast Sunday that building a wall along the U.S. border with Canada is something worthy of further study.

“That is a legitimate issue for us to look at,” the Republican presidential candidate said on NBC’s Meet the Press program.

Walker said the issue was raised to him during a campaign event earlier this month in New Hampshire. He and other Republican presidential candidates have more commonly called for building a wall along the U.S. border with Mexico.

Now it’s true our northern border is vastly less supervised than its southern counterpart. So if you view the rest of the world as a seething cauldron of evil untermenschen scheming to get into our country to blow up things, breed anchor babies, go on welfare, and impose Shariah Law–not necessarily in that order–then it makes perfect sense to start worrying about lesser breeds sneaking over Alberta-Montana border. In the shorter term, Walker may have just given Canadians a new issue to talk about in their own national election campaign, due to conclude on October 19.
