What's he doing? Usually (for him) doing something as stupid as closing the border is associated with some kind of pending deal but there is none. He'll create a huge clusterfvck if he starts closing entry points then just have to open them back up and be right back where he started. I see it as a big bluff but for what purpose? I guess he sees immigration as the Repub's big issue going into 2020 and he wants to make a big of a mess of it as he can between now and then and then say only he can solve it? If that's the case then he's going senile and the Dems are cheering...
