Where's the evidence? When AZ passed SB1070 the illegals fled like roaches with the lights turned on. Most went back home.
Others fled to CA and other states that weren't enforcing immigration laws. Then, Holder's Dept of Just Us stepped in and put a boot on the throat of AZ. The law WAS working, and it mimicked CURRENT US law!
I'll say it again, slower...
IF....YOU....STOP....THE....INCENTIVES...THEY'LL....LEAVE.
