The Democratic Party has for some time now been a moderate conservative ( business ) party.
The Republican Party is now officially a fringe extremist fascist party.
Seems like now would be a good time to launch an authentic liberal ( people ) political party in the U.S.
( psst, hey Bernie! )
You can have good business and humanity, the democrats just need to realize that subsidy's to military, private prisons, the health insurance industry and fossil fuels is throwing money down the drain. Every country has some mix of socialism and capitalism and it's how competently they use both rather than some test of ideological purity that leads to good quality of life. The current maga cult republicans have reached a level of corruption and incompetence that the smart money is getting rid of them first. They're a gangrenous limb that needs prompt removal.
America is a centrist country and will be as long as religion has a strong hold on the people. If you split the Democratic party we will be in the same mess the Republicans are in. In effect they are a split party, and they lost the House in 18 and the Senate and Presidency in 20. Maybe our form of government doesn't work. There are over 160 democracies in many different forms on this planet and we were the first modern democracy, yet not one has copied us. I wonder why!
Let's make sure the stake is securely penetrating the vampire's heart before risking a loss, especially while Trump is still hoping for another run. You can be sure the Republicans will be doing all they can to splinter the Democrat Party. This is not the time to help them. If you love progressive ideas, promote them from within.
