Lefty Stevie, a.k.a. SKB must be crushed to see a devoted fellow Liberal like King admit that Walker didn't actually say we need a wall between the U.S. and Canada. The "worth reviewing" part includes border security everywhere... not just the relatively low risk Canadian border, and the fact that as many as 30-40% of illegals came in under visas which they overstayed.
The Mexican border is as porous as a tennis racquet, and the easiest obvious choice for brown skinned Islamic terrorists to enter. But the problem is widespread, and when, not if there is another attack, there will be another Patriot Act type of over-reaction to today's sheer negligence. Then the Libtards will be whining about infringements upon free speech, privacy, etc. I will agree with them on that, but I will also know that it was largely their inaction and their support for open borders that precipitated it.
