It's been the center piece of Donald Trump's entire presidential campaign: We're going to build a wall and Mexico is going to pay for it.
But according to a new CNN poll, the idea of a border wall along the entire southern border has significantly decreased over the past year. A year ago a majority of Americans favored a wall. Now, a majority are in opposition.
But the biggest issue for Trump isn't simply the wall, but instead that voters are split almost evenly when it comes to who will handle the issue of immigration best as president. This explains Trump's "softening" and change in position on the issue over the past few weeks.
There's a tight split among voters over which candidate would do the better job handling immigration, according to results from the same CNN/ORC Poll released Monday. Among registered voters, 49% say they trust Clinton on the issue, 47% Trump.
It should be noted that support for a border wall was at an all-time high in 2006 during the passing of the Secure Fence Act, which allocated money and other resources to securing the southern border with Mexico. Democrat Senator Hillary Clinton supported it.
"I voted numerous times when I was a senator to spend money to build a barrier to try to prevent illegal immigrants from coming in. And I do think you have to control your borders," Clinton said at a campaign event last year.
