Is DC a union only area? Hell, most contractors in Nashville use illegal Mexicans and have since 2000 because Americans rarely work. Try to hire American roofers? Try to hire American drywall types. I cannot find them as the owner might be American, but; his labor is illegal Mex.

The only workers in DC appear to be 4 illegals to 1 American. This proposed union is Hispanic etc.
The NRO has already endorsed Cruz.
