A good start, but to really do any good, you need to get rid of 3/4's of the House and Senate. That includes most Republicans as well.
And thats it in a nutshell. Our county sheriffs office catches smugglers all the time headed north. They arrest the smugglers and seize their vehicles, but have to release the illegals unless they're wanted, or on a "watch list".
Goldie lives closer to the border than I do, and likely sees more than me, but much of our crime is from the illegals trying to get through our very rural county.
