For those wanting a wall, this is 2019, not 2019BC. A wall will not: stop river crossings, tunnels that already exist in the wall that is there so tunnels won't stop them and neither will the height of the fence. Technology, money for stronger Visa controls is the way of the future. We are a country who WELCOMES people who believe in democracy. We don't turn out backs on people. We turn our backs on policies that hurt people. Any one that believes his wall makes a strong President, is mistaken. A President that needs a wall, is a weak President because bluster is not good leadership.
