You know it is a terrible idea if Scarborough thinks it is bad. Even if you like amnesty, which I do not, it is a bad idea to pass it now because:
1. Obama is one the ropes and the voters are upset over Obamacare. Passing amnesty redirects the attention from Obamacare.
2. In conjunction with 1., passing amnesty gives Obama a victory, a legislative legacy. Obama now has the appearance of leadership, inspiring the democrat base to turn out in force.
3. in conjunction with 2., the GOP looks increasingly like an Obama lap dog, weak, tepid, uninspiring and the GOP base stays home.
4. In conjunction with 3., amnesty creates a GOP civil war, dividing the GOP and causing internal strife. With no unity, the GOP turns on each other and loses whatever political gain they have accomplished to date
5. In conjunction with 4, massive energy and resources are focused on the GOP civil war and amnesty, energy and resources that could be directed to more important, vital Conservative issues.
6. A strong turnout by Hispanic voters in the midterms, "thanking" the democrats for Obama's leadership and accomplishment.
I really cannot think of any positive point to passing amnesty. And, this analysis omits the obvious dangers of passing amnesty, a failed idea since 1986.
