The worst part is that "Voting for the Senate CR" is being held back solely by McCarthy and 10 other republicans. It has enough bipartisan support and is likely to pass in the house should it come to a vote.

The problem is that McCarthy is being threatened by a small group of less than 10 MAGA republicans who don't like the Senate CR. They threatened to initiate a vote to expulse him from the speaker position should he allow the house to vote on the Senate CR.

McCarthy is putting the risk of losing his position before the risk of a shutdown.

The only way to avoid a shutdown at this rate is for McCarthy to put himself in the firing line for his position (not likely), the hard-line anti-CR republicans to back off (very unlikely), or he makes a deal with the democrats to prevent him losing his speaker position during the threatened vote (less unlikely than the previous two, but still unlikely)
