From Schumer's op-ed in the times:

1. They want a shutdown: If the WH wanted a shutdown, they'd have given a worse bill. Instead, they want a green light from dems to continue letting DOGE and Trump run roughshod over the government
2. Dems can't be blamed if they sit back and watch: Has he not been paying attention? Dems are blamed no matter what. If they vote for cloture and the CR, the GOP & Fox will blame the dems from not stopping the GOP from hurting themselves (Why didn't they stop us!?).
3. Government employees will be hurt: MFer, they're being hurt now. 

I've been trying to call all morning (from someone who hates talking on the phone). I keep getting a "we're not here now or are busy" message. Will keep trying.
