The only factor I can reason that has forestalled our inevitable destruction is God Himself. If and when we have another illegal alien terrorist attack I would not want to be a politician in office period, democrat or Republican given these open borders. The blame will be placed squarely on those in Washington who did not do more to keep the bad guys out, even if some wanted to, like Tancredo.
Friend, I hope that you're correct. But since I have no recent precedent of the serfs bringing the rulers to task, I must conclude that we vestigial Americans will continue our butt-slide into history's ash-can.
