Once a VP, becomes Pres. , there is NO VP, the speaker is next in line--the DEMs will lose their tie breaking vote--looks like we're stuck with Joe till the 2022 elections
The speaker could be the next press., the next VP would have to be nominated by the senate--Mitch would be in the cat bird seat--best solution IMHO, Trump runs for congress in 2022, if he wins he would be a cinch to be speaker of the house--then Joe would double his depends order
