On Tuesday, Virginia gubanatorial candidates Jerry W. Kilgore and Timothy M. Kaine debated with Tim Russert as moderator. One of the main topics was illegal immigration. They both pledged to crack down on businesses that knowingly hired illegal aliens, but somehow I trust Kilgore's pledge quite a bit more. Kaine wants localities to determine what's best for their communities. That would allow, for instance, Herndon to establish a day laborer hiring hall knowing full well that most of those using it were here illegally. Kilgore doesn't think that's right.
