B$. A start would be to militarize the border. Declare Martial Law along the entire border and police it with the military.
We don't need high tech cameras to monitor illegals crossing the border any kid with a smart phone can record that activity, it is what happens after they cross the border that matters, nothing else.
I have never though the wall will solve the immigration problem because there are many avenues into this country. What happens to them after they get here is the problem. Most children born here last year are anchor babies how do we survive that? They do not grow up and vote Republican.
I purposely turned all news from cable or network off 4 days before the election and waited to hear if the Country had voted to survive or commit suicide. Suicide it was because either the Democrats figured out a way to steal the election or we had truly became a Socialist majority Country, neither of which can be overcome with ballots.
