I’ve come to agree with George Washington. Political parties are a menace. FWIW, I’d concentrate on expanding the number of pols who’d vote with him on his issues irregardless of party. Vote with him, you’d have his seal of approval. Vote against him and you’re toast. To Hades with party affiliation.
If the party becomes more vibrant without a small group taking complete control then there are advantages. It is when a party is controlled by a rather small cabal of players that it becomes stale and ineffective. That had become the problem with the Republican Party. Time for new blood at the top, and to keep changing that blood with new blood more regularly. Not so much for the sake of the party, but for the sake of the nation.
