50 votes that includes Joe Manchin, Sinema, etc in the Senate is not control. The last time they had an actual fillibuster proof majority they passed the ACA, which would have included a public option if they had another vote. And that period where they had control lasted a few months, not years. The idea that Democrats don't pass legislation when they aren't being blocked by the domestic terror cell they have to work alongside is completely ahistorical.
