“Manchin apparently wants to run for governor of WVA.”
Joe Manchin was WVA governor for two consecutive terms starting in 2005. He is ineligible to hold that post again.
Furthermore at age 73 he has a sweet deal going in the Senate. He can stay in the Senate until he’s hauled out feet first.
Manchin either wants to be President or the next Byrd.
I think his Prez dream isn’t remotely realistic. (But if you have a delusion it might as well be a big one!) Being the next Byrd is much more doable, though he has competition for that with Capito. I am not sure who has senoirity, I think they’re pretty close to each other. Whichever one finds a way to permanenantly attach themselves in some way to the Senate Finance committe will win that derby. (Both currently serve on it!)
