ICE has been hobbled since it was created by GWB.
They can only deport the worst of the worst.
President Trump has done what he can to secure the border, but interior enforcement has not increased significantly.
If sanctuary cities refuse to refer illegals they detain to ICE,regardless of their “quality”, ICE can’t deport them..... unless they just stumble upon them. You can’t blame the FEDs for 99% of the problem.
Californians demand for cheap labor drives the supply. FEDs don’t demand the supply.
