When I was delivering Papa John's Pizza parts (big truck delivery to impossible to unload safely hide-a-way places in large cities) .... in the Virginia/Baltimore/Washinton areas, There were a TON of painter type Mexican looking crews everywhere
I saw the same in Texas
I'm sure (or almost sure) these outfits are centrally controlled/watched (like taxi medallions) by one or a few entities
If THOSE guys are on Trump's side ... the statement is true
His stand on ILLEGALS is what has endeared the legals to him. They are not stupid. They see what is happening to them as a group.
The key is that the 50% that side with democrats are going to side with democrats no matter what.
The democrats hammer the GOP over the head with sending mom, dad and the children back to Mexico (whether it's true or not) and the GOP HAS to continue to hammer the danger that open borders cause. The felons, gang members, violent criminals and other human debris have to be talked about over and over. This is definitely making a difference to mainstream, educated, Americans of hispanic descent.
Secondly, the other message that has to be conveyed is that if you really "care" about how illegals are put into danger by crossing illegally with coyotes or other unsavory types that rob, beat, rape and kill them, then HELP them! The only way to help the honest hard working illegal is to secure the border, give them a guest worker permit and safe passage in and out of the country. To do less is heartless.
There's absolutely nothing wrong or detrimental to knowing WHO is coming into this country. A guest worker program has to put into place. We can build a system that allows illegals who work to come and go as they please and keep the riff-raff out.
