the Dems could negotiate real issues among themselves and come to a consensus agreement (e.g. Infrastructure and BBB)...it is totally normal to have a range of opinions even within one party, but for the Dems, they don't threaten each other with "Primaries" or outright eviction, simply for their views on an issue of basic democracy...or human decency.
You should be working very hard to do what you can to fix that disaster...we need two 'sane' parties that represent ALL of America...right now we have only the Dems.
