Why Border Walls – Even With Canada – are not the Republicans Trump Card

Republican frontrunner Donald Trump says Mexico must pay for a wall, while fellow Republican presidential candidate Scott Walker took it up one notch and said that the building of a wall on the United States border with Canada was “a legitimate issue. However, costs, practicalities and history say this would be a monumental task. Politicians in the US have long dreamt of constructing a barrier on the nations southern border, to keep out illegal immigrants from Mexico and points southward. But some academics and Republican politicians argue that such a concept – to erect a physical blockade as successful politics – may be ineffective. Despite the novelty value of proposing a wall along the Canadian border, and the controversy that Walkers comment has already prompted on both sides of the issue, the Wisconsin governor was addressing an increasingly familiar refrain on the contentious election issue of immigration.\r
