They also want tens of millions of new consumers, even if they get their spending money from Americans trying to pay their bills. With unemployment as high as it is, and the economy asa sluggish as it is, these illegal invaders are now prized as re-distributors of the wealth of those still working. In my area the illegals are needed to keep housing and classrooms occupied.

Can you imagine what our politics would look like now, if they'd been taken seriously?
