I propose we use illegal alien Guatemalans to build the wall, using Joe Arpaio type tent cities. /Sarcasm
the way things go here, the contract would go to a company who would hire illegals to build it. they'd tell all their buddies how to circumvent detection and each Congress critter's district the fence went through would get kickbacks from said company.
also, Dims would demand union-only companies get the contracts to insure if costs more than the Big Dig yet still has plenty of flaws and runs over budget and takes at least 25 years to finish.
Lastly , all the parts to maintain and assemble the parts would be made in China and Mexico and the Supreme Court will rule it's all somehow "unconstitutional" , but only after it's finished.
Guatemalans in pink...LOL
