Don’t forget what he told Bill O’Reilly, as reported by CNN
CNN, 8/5/2015
“Trump: Mexico will pay for wall because I say so.”
./s (From Matthew 8: “And when Trump had spoken to the winds and they calmed, the disciples said: Even the winds and the sea obey him!”
See, Trump speaks and Mexico pays for the wall, just like the winds and the sea obey him!) /s. LOL.
It's not inconceivable. He could slap a tariff on cross-border trade with Mexico. The US imports almost $300b a year from Mexico. A 1% tariff over 10 years would fully fund a fence.
