He knows. He doesn't care. This is obvious from the fact that he continues to preach to us about "terrorism" despite leaving the borders wide open, even after 9/11/01, for anyone and everyone to stroll across.
This is no American president. His loyalties lie elsewhere.
As long as he does not shut the borders completely down his WOT rings hollow. I can no longer take him seriously on this issue and neither do the American people. Ever since he started on this amnesty bill, his poll numbers have taken a dive. Iraq is not why his ratings stink--it is the immigration problem.
In my GOP circles, which are quite large, almost everyone is fed up with him. The mantra is: "We did not vote for out of control spending and open borders."
