Give the Democrats a 4 person majority then 5 conservative Democrats will Hum and Haw about fiscal responsibility to their voters.
It is really up to hard progressives to get in and vote as a block to keep the Dems from passing watered down policy by forcing them to earn the blocks vote with real policies the public already want.
Medicare for all, free college, 20 dollar minimum wage and more all all supported by way more than 50 percent of the country.
The Dems want to lose these fights for their donors they need to be forced to do their job against their donors wishes.
