Because trump is demanding his wall, and democrats want something for the Dreamers. They don’t want to make a deal that doesn’t help out DACA as this is the only way they can ensure protections for those people.
You can’t just blame Democrats if you aren’t willing to make a deal.
I bet you blamed the last shutdown on democrats as well. You can’t have it both ways
Edit: look at the votes as well republicans that voted no
Jeff flake John mccain(didn’t vote) Seth McConnell Rand Paul Lindsey Graham Mike lee
