Fences work and I have experienced it. Prior to the latest being built in San Diego County we were being overrun here in East County. I haven't seen an ILLEGAL alien near my home since as they have all moved further east into the desert where there is no fencing.
I wonder...how many of those who defended La Raza Rick Perry's anti fence position now support a fence because liberal Donald Trump is for it. They only opposed it because their pro-ILLEGAL alien governor Perry did so I'm sure there are some.
Anything to keep actual conservatives out of power, we can count on the same group to be there doing it.
