Oh dear, I hope you don't think that the wall will stop the problem completely.
I will assume you are not that stupid so the question is, how much of the problem will the wall solve? next question is is it worth the cost?
I don't live in the USA, have no desire to go there and don't care who votes for who. I simply make the observation that the wall is an expensive waste of an idea that while it may stop a few illegal immigrants will not solve the problem.
