Bush is using his same old attack line against people who oppose the immigration bill:

This reform is complex. There's a lot of emotions around this issue. Convictions run deep. Those determined to find fault with this bill will always be able to look at a narrow slice of it and find something they don't like. If you want to kill the bill, if you don't want to do what's right for America, you can pick one little aspect out of it, you can use it to frighten people. Or you can show leadership and solve this problem once and for all, so the people who wear the uniform in this crowd can do the job we expect them to do.

Now the righties are seeing how it feels to have your patriotism questioned and they don't like it.
