Not quite. These folks aren’t thinking about Congress as a whole. They are thinking of their own position, and only their own position within the Congress. If you were a Whig in the 1850s, and didn’t care much about Slavery, and didn’t want to be a Democrat, the Republican Party would not be a welcoming home. You might join them, only to be always looked at with suspicion, and never earning respect, or you might retire.
We are looking at a Party Realignment in action. Goldwater started it, Reagan catalyzed it, Trump is working to make it stick.
Yes. Agree. I haven’t yet seen a single MAGA retire-—all Dems and RINOs.
