It seems the right is not only demanding perfection, they are being very rude about it. These folks have led the GOP to one election defeat, yet they continue scorched-earth tactics that will not only ultimately fail, but which will also eventually make Hispanic Republicans are as rare as black Republicans.
That isn't the only people who will be driven out of the GOP. Moderates, the business community, and farmers will also take their political support elsewhere. And thus, the hard-liners will have their pure party - and will also be a minority. If anyone needed any proof that the base of the Republican party is as blind on immigration as the base of the Democratic Party is about the global war on terror, one just has to look at how they are acting.
