Scott Walker on Sunday said he was considering a fence on the border with Canada:

"Some people have asked us about that in New Hampshire. They raised some very legitimate concerns, including some law enforcement folks that brought that up to me at one of our town hall meetings about a week and a half ago. So that is a legitimate issue for us to look at," Walker said about building a wall along the Canada-U.S. border.

Note the key phrase: "That is a legitimate issue for us to look at."  Now Walker said he was misunderstood, and he wasn't considering it at all.

A spokeswoman for Walker's campaign said that he wasn't calling for a wall specifically, he was just expressing concern over the issue.

"Despite the attempts of some to put words in his mouth, Gov. Walker wasn't advocating for a wall along our northern border. Chuck asked about it and Gov. Walker said based on what he's hearing from people there are security concerns that need to be addressed," AshLee Strong said to POLITICO.

Every candidate makes a slip of the tongue from time to time, especially given the stress of running for president.  But Scott Walker does it all the time.  He's had more back-and-forths on immigration than all the other candidates combined, even more than Donald Trump, who at least can stay consistent for a whole week.  On birthright citizenship alone Walker had three positions – no, maybe, and yes – all in less than a week.

From reading the comments, I see many readers have changed positions, too – many of you used to support Scott Walker, and now no longer.

It is no longer an issue of whether it is ridiculous to call for a border fence with Canada when the main trouble is with Mexico.  It is no longer an issue of whether Walker is tough enough on immigration or not.  If you read everything he says and assume he's being consistent throughout, then we are left with one conclusion: he is incapable of speaking clearly.  That, I think, disqualifies him from being the nominee.

Scott Walker has been great for Wisconsin.  I think he should go back there and stay there.  Clearly, very, very much so, he isn't ready for primetime.
