Okay, I'll say it.
No it's never been money. It's always been about not allowing Trump and his followers this victory. That the wall is rooted in lies, fears, and racism is beside the point. Giving Trump a victory, such as this just really can't happen.
Part of me wants them to move on, give the money, and negotiate something in return and let Trump build that wall and satisfy his base.
The other part of me is behind them. I couldn't stomach him having this victory. That might be catty, but if it were truly rooted in concern for the welfare of us, and a national emergency I might feel different. Trump wants the wall, that he'll declare a false emergency, lie and whatever he can because he can't stand to lose.
