The facts are always getting in his way.
The border fence is a bargain BTW because not only does it make it harder for illegals to cross over, but acts a deterrent to people thinking about crossing in those sectors. Additionally, for every illegal who stays home, the American taxpayer saves a tremendous amount of $$$$ both immediately as well as for years to come.
If a person wants a stampede of 3rd world peasants into the USA, like Decker does, than of course you are going to try to find every excuse under the sun against a fence and wall.
