I'm surprised that the Democrats havent thought through that. They could have all the sheep come in and register, then issue them passports or breeding visas which they would display for free passage to mexico, and when they have their fill of nookie, they would have free passage back. Simply show their papers at the gate.
"cactus pygmy owl, Sonoran pronghorn, flat-tailed horned lizard . . . "
Well, how bout letting the owl fly across the fence, the lizard crawl through it, and capture some wolves and jaguars and release them on this side. What a flimsy attempt at ending any attempts at stopping the flow of illegals.
But registering would create a hardship for underprivileged and low income bighorn sheep
Fine........lets have a thirty day open season on the sheep.......then build the fence!
Or better yet a thirty day open season on enviromentalists and libs.
