McCarthy wanted the job too badly
Why he would want such an impossible job I have no idea, but he coveted it for a long time. Perhaps he thought it would look so great on his resume. Not so much now that he is the first SotH ever to be kicked out before his term ended.
Now Jim Jordan wants it. The guy accused of turning a blind eye to the sexual abuse happening on the wrestling team he coached, not to mention his connections with Jan 6. And Steve Scalise, the poor bastard who got his dick shot off by a left wing shooter at the Congressional ball game a number of years back.
And of course Trump would consider taking the job if he could encourage some nut to kill Biden and Harris and make him president again.
