Walker: building a wall on Canadian border is worth considering

[Why]

There has to be only one thing sillier than building a wall along the whole Mexican border and that is building a wall along the whole Canadian border. Although if Walker becomes president then he might want to build the wall stop everyone leaving to go to Canada.

Then put a big plexiglass dome on top of the US ?

Yes, of course. They can even make a TV series about the new American called Under the Dome
