I'm of the opinion that neither side really wants to "fix" immigration. It's a canard. One side has successfully used it as a wedge issue to win elections. The other, I think, at least tries to make things slightly more humane.
If immigration was really a huge problem in Texas, the GOP would've done something measurable about it in the last 30+ years it has been in total control of this state. Also, several key Texas industries are about to have their pee-pees whacked if Trump follows through on deporting tens of millions of illegal immigrants.
(FTR, I'm all for making the immigration process simpler and more manageable. I also don't know how to do it other than make the path less murky. Let's have them get taxed more easily. But part of the allure to the current system is that they're not paying taxes for basic municipal services. They're paying sales taxes on all goods purchased but most everything else is under the table. But, the flip side to making everything above board is that costs will go up for everything.)
