There is the Uniparty, and then a bunch of theatrics and manufactured crises to keep the dramatic tension between Dim and Repug supporters, so the Congressional workers can claim to be "doing their best".
What was the substantive difference between Pelosi and McCarthy? What is that differential between Schumer and McConnell?
They all seem far more similar than different, with very little noticeable difference.
The only point that I can recall as being substantive was Uncle Mitch on Scotus replacements. But everything else was industinguishable from Crying Chuck.
