Kind of hard to close the border when you are only one person, the four largest cities are run by Democrats and are sanctuary cities and everything south of Houston is pretty close to all Democrat and Mexico. Been to Brownsville lately? If not, take a visit down there, stand on the bridge going into Mexico and just pretend you are the Governor and you are there to announce that you are going to close the border. IMO it was easier to close the border between Iran and Iraq. Best thing we can do for Texas’ illegal immigration problem is to get rid of the Democrats in Congress - both Texas and Washington.
I haven’t been to Brownsville lately, but have been to El Paso. It is just about as bad there. I agree with voting every dim out of office, even the local dog catcher.
