Jared: Only someone who doesn't know anything about the size and scope of these issues could so arrogantly say that they could solve them in that way. I'm all for optimism and bringing a new face to things, absolutely without a doubt. But a wall with Mexico that Mexico will pay for at the end of my first term? It's hard to believe anybody serious would fall for that unless you were deliberately wanting to just believe whatever was being fed to you or you just hadn't ever thought about these issues before.
