I tell you what banana mach II: If Trump wins again in 2020 then I will drop any and all arguments to building the wall. If he loses and there's no wall by then the only one to blame for that will be him: He got elected, he had the house and senate and he failed not only to lock Hillary up but to build the wall. It'll be something for him to mull over while he spends the rest of his life in court.
