They voted on party lines. They would rather the House be shut down than the republicans be able to pass a working budget in 45 days, they think they can "blame it on the republicans"... however they voted to shut down congress today, every D in congress voted with 8 republicans to literally shut down work in the House of Representatives.
If Republicans need to get the House they are in charge of up and running, maybe 8 of them will find a way to vote for Hakeem Jeffries and get this moving.
That is about as likely as Democrats voting for Kevin McCarthy.
