Amid the growing debate over building a wall on the U.S.-Mexico border, a new poll shows that voters who strongly favor building such a wall cannot successfully identify the border on a map. Additionally, the more enthusiastic voters are about building a wall, the less likely they are to know where the border is actually situated, the poll finds. Voters who could not correctly identify the U.S.-Mexico border provided no fewer than fifteen alternative locations for it. Nearly twenty per cent of respondents located it along the United States border with Canada. Being told that they had incorrectly identified the U.S.-Mexico border did not in any way dampen voters enthusiasm for building a wall there, however. To the contrary, voters believed that it would be easier to locate the border once it had a twenty-foot wall. Among voters who could not correctly identify the border, there was strong support for the Presidential candidacy of the billionaire Donald Trump. Ninety per cent of those voters strongly agreed that Trump knew where the border was, as opposed to only four per cent who said that about Wisconsin Governor Scott Walker.
