You pretty much nailed it. There is simply NO WAY 56% of American voters are opposed to a border wall. That is like saying most Americans would like to slit their own throats.
The polls used to show it the other way. They just dialed the polls to fit their agenda.
I would say 90% of Americans, esp Latino citizen, are in favor of strong border security. The president wants funding that includes building a fixed barrier in various places. THe money is really small in comparison to the rest of the budget.
Why don’t they give him what he wants?
