I wonder if this will still be true for Democrats when the shoe is on the other foot. They were held together by Pelosi's skilled hand for twelve years. I think the fundamentals are strong for the Democrats. They care a lot about good governance principles. Ultimately, I think that will keep everyone on the same page. I don't see any part of the party willing to rock the boat.
Where I am starting to get worried is with the national debt. The US, China, and many other governments are going to run into both debt issues and an aging population. That will force a reckoning at some point on entitlement spending, which is very popular.
The solution to the debt is taxing the rich, and equitably too. They're going to have to pay double for the amount they've stolen from we the people since 1980.
