He had this idea about solving three problems at the same time:
1. the immigration problem:
tear down the fence betwee Texas and Mexico and dig a big moat filled with water.
2. New Orleans problem=below sea level:
use the dirt from digging the moat to raise New Orleans above sea level
3. Florida's alligator problem:
Put the 'gators in the new moat.
Solves all three problems at once....sounds like a plan to me.
