Meet the new boss.
Same as the old boss.
The problem isn't the boss. The problem is a badly divided caucus that makes it impossible for
any Speaker to forge a GOP-only majority on individual spending bills.
And it isn't that Johnson doesn't have enough time to pass individual spending bills. It's that the conference doesn't agree on the spending within
any of the remaining individual appropriations bills.
That's the exact same problem faced by McCarthy. The moderates in the conference never liked the concessions that McCarthy made to the hardliners back in January, and got tired of deferring to the conservative hardliners just so McCarthy could meet those demands.
Once the hardliners voted down the CR bill including 8% cuts put together by Chip Roy, and forced McCarthy out, the moderates justifiably concluded that there was no more reason to defer to the hardliners for the sake of conference unity. So now, it is impossible to put together a GOP majority on those individual spending bills.
The different factions within the GOP conference have decided to stay loyal to their respective constituents - whose views differ greatly from each other - rather than to the conference itself.
This is exactly what a "no compromises/no 'coalition" caucus looks like.
