Oh. Wait. Now you are telling me that there are a separation of powers and that President Trump hasn't had the last word on this? Well sakes alive. I had no idea.
That’s entirely the point. He won’t have the last word, because he takes a hit on the right, either way. There’s no massive support for a shutdown from this Congress. That’s what a veto gets. It’s not the same as December, when a lot of them were out the door, anyway. He’s not getting the full support from McConnell this time around, especially after a bipartisan group worked out this deal.
Signing it draws fire from the base. It’ll only get worse when he pulls this weak executive move, over an actual emergency declaration he’d promised before. I haven’t seen someone neuter themselves like this since Marshall Applewhite and Hale-Bopp.
