I'm not averse to having the Republican Party go the way of the Whigs and have something better replace it. But not sure how practical that is.
Its totally practical. Unless one thinks they fall under too big to fail.
I see no point in overhauling it. You would need to fire 90% of the people behind the scenes to avoid sabotage and then you are stuck with the legacy.
Yugo could start building Bugatti/Ferraris and few would by them. Same reason. Brand damaged beyond repair.
Why not take the very same resources and start clean?
