“Their party unity is over.”
I have heard that prediction so many times before. It never works out that way.
This is less contentious than the battle for House GOP leadership was in 2017. And just like 2017, the Republicans will fall into line and support their leadership.
Sadly the House GOP will do nothing with such a slim majority.  And the voters will have to wait until 2024 to vote him out, if he doesn't resign. >

The NYT just reported the Republican Nassau County District Attorney is investigating Santos. The Republicans desperately want him out in any attempt to retain the seat. They can appoint a replacement with a prayer of winning next time. >

There will be a special election more than likely.  The GOP isn't going to risk their slim majority on the hope of winning a special election.  Especially after this shit storm. >

The majority is slim, but not that slim. They can afford to lose one seat. And McCarthy surely can’t expel him until after he wins leadership. I think if he just keeps his cards close to his chest he will have the option. >

You've seen how the Democrat senate struggled against Manchin and Sinema right? The House Republicans are treating Sinema as their role model, all of them want a pound of flesh from the Speaker. Personal concessions on everything. 
Their majority isn't that slim, but their party unity is over.
