I totally understand that.
But there is a reason we have borders. Mexico has borders which they enforce, and so does every other country on earth.
We have locks on doors and fences with no trespassing signs, and we have borders for a reason. I will not vote for anyone who doesn't know that and understand it.
Mexico loves the people who illegally cross their southern border so much, they arrest them and then prosecute them to the fullest extent of the law.
