As long as republicans continue to say no to that, it's impossible to do. Democrats basically never have actual control over the American Government, it's happened like 4 years out of the past 20, and that's not a new phenomenon. Even in the times they have had "full" control of all portions of government, republican senators are still able to "block" stuff through made up rules and "norms" that democrats don't want to break, because that gives republicans cart blanche to break those same rules in a way that can do a lot more harm. Also like 4 of the democrats that are part of the "majority" for various reasons like to be contrarians to the rest of the party, meaning even the few times there have been a majority of democrats in the senate, there has not been consensus in the party for basically anything since probably FDR.
