I think you need to be reminded for whom our Representatives work. They don't work for a party they work for the people of their jurisdiction, the electorate.
You wrote "come down harder on some democrats.......because they need to be reminded just who they are working for." Those Democrats do not work for the party, they work for their constituents almost half of whom are Republicans. Take Joe Manchin, he does not work for the Party, the party is supposed to work for him. He works for the people of West Virginia. The Party should be helping him support his constituents with legislation that fits their wants and needs.
With this "good on you for voting for Biden. You are proof positive that some people do understand how dangerous the repub agenda is." You completely misunderstand my vote. I voted for Biden not because of the Republican or Democrat Agendas. I voted for Biden because Trump is unfit to be president. If the choice was between Susan Collins and Joe Biden I probably would have voted for Susan Collins. I support a number of policies that Republican support and Democrats oppose. Less so today than in the past as both parties have moved to the right.
