I’m not so sure about the second part of your statement.
You are absolutely correct the RINO moderates loathe the Conservative core of the party.
However, I think Jordan sees that making the compromises necessary to win 217 votes is what killed McCarthy. McCarthy owed way too many concessions to the likes of Matt Gaetz including single-issue voting, an orderly appropriations process, etc. Jordan didn’t want to go down that road. He is already Chair of the Judiciary Committee. That gives him lots of power. He doesn’t need to sell his soul for a bigger office.
Good points!
