This is game theory. RINOs vote for mccarthy to keep their PAC money flowing into their pockets, democrats are ok with mccarthy because they can buy him off and still get some of what they want but would rather someone on their side as speaker so they can get all of what they want instead.
The 8 are part of neither group. They voted to get mccarthy out because he votes with democrats 45% of the time (there is the “some” part) and they hope to get the RINOs to maybe vote for a speaker who will vote less with democrats.
And that is how it works.
Reality is that the next speaker will be in an even weaker negotiating position vs the democrats.
As to voting, Repubs only control 1/3 of the government and with these idiotic 8 bomb throwers, it was a very tenuous majority
Re: 43 - a link that McCarthy votes with Dems 45% of the time?
