I agree with you completely.
If we can't enforce the laws we have now,and can't enforce the borders that hold thep people who live under the constitution what makes anyone think a new amendment would make a difference in the reality of the situation.
Maybe 75% of americans don't want illegals...but no one is protesting or getting active. We can't even get the federal govt to pay the states for their housing illegals in their prisons and jails or help with their hospital budgets.
Well, there is the Minuteman Project, among others. There are also several candidates who are running on this issue such as Randy Graf who is running in Arizona's District 8 which lies right on the border.
