"Do you also want to stop all LEGAL immigration too?"
I have zero problem with LEGAL immigration. I helped start a spanish TV station, a Mexican restaurant, and I'm fairly fluent in Spanish, so just forget the racist crap.
Highways cost $1 million a mile. $2 billion for a fence ought to do most of what is needed, a pittance amortised in a 2.7 Trillion dollar economy.
It's not "racist crap" - I will get you and nicmarlo the link. Perhaps you missed where it would cost $80 billion, let alone what "sealing off the border" would mean to the rest of our economy?
