If (as you claim) the wall will do little to nothing to stop the flow of drugs and illegals from entering the country. . . How do you expect mere laws with no physical barriers at all to keep guns out of the hands of criminals on the streets?
You have some splaining to do!
I'll explain. It's as usual in these kinds of things a straw man. Find me a single Democrat who says that the only thing that needs to be done to stop illegal immigrants is impose mere laws?
Democrats say that the wall is not the most efficient ways to battle illegal immigration. Not to mention that before the Democrats proposed 25 billion for a wall in exchange for protecting Dreamers, something that was rejected by this same president, after he first tentatively agreed to it. By the way Trumps mercurial nature makes negotiating with him a risky process to begin with.
