This is big news. Sensenbrenner has let the cat out of the bag and I suspect what Rove is attempting is not going to play well with the House leadership.
Personally I hope Rove gets his fingers smacked by the mousetrap.
Remember a few years ago when Karl Rove warned Tom Tancredo never to darken the doorway to the White House again because of Tom's anti-illegal stance? Bush and Rove are very pro-illegal alien, almost, pro-Mexico in their stance.
But Bush is in a catch-22. The House, hoepfully, will not back down. The GOP stays in control. If the house caves, a lot of GOP congressmen will lose their seats for being pro-illegal. If the house is lost and the Dems get control, they will push for impeachment. So bush has to face political realities. Either he doesn't get his way on immigration or he may have to face the prospects of a Dem controlled House. Sadly, it's the Senate where the spinelss ones grow.
