Trump is the one that needs to grow up,
What does Trump gain if he re-opens the government? He has all the money he ever needs. He already has a legacy. He is the first elected president with no government experience. It doesn't matter to him if he gets re-elected or not. He didn't even think he would win the first time. If this shut down last until 2048 then it won't hurt Trump one bit.
What does Trump lose if he re-opens the government? Nothing. He is in a pretty sweet position.
There is nothing for him to lose or gain if he re-opens the government. Democrats need to throw him a bone. I bet he can be tricked into it somehow. Surely there is something he wants that is cheaper than a wall. Any suggestions?
If Trump doesn't care then we have to make him care. Give him something good.
