Hear hear! Another excellent idea—we too often focus on the President, yet other than appointments (which, as Jim R. has pointed out, is extremely important), the CONGRESS is the source of power in our Government. Focus on where the problem is, NOT where the symptoms are!
Perhaps a Border State Convention should be called to address the issue. Delegates from various states could be appointed to represent their respective states. The agenda would be limited to the issue of illegal immigration: problems and solutions. This might get the discussion going and get the states (ie. the people) moving in the same direction.
