Yes, finally we can see the proof- the Bush administration policy to bring illegal immigration to a standstill has paid off:
"Net Migration from Mexico Falls to Zero—and Perhaps Less...The largest wave of immigration in history from a single country to the United States has come to a standstill. After four decades that brought 12 million current immigrants—more than half of whom came illegally—the net migration flow from Mexico to the U.S. has stopped and may have reversed."
And all Bush and Cheney had to do to accomplish this amazing feat was crush our economy so there were no jobs to be had here! Why couldn't those Democratic smarty pants elitists have thought of that? Once again, proof of the superiority of Republican policy.
