Joe Biden and the Democratic Party hold power in Congress by a “hair”, with an evenly split Senate, and only a few votes margin in the House of Representatives!
So if one Democratic Senator was to be incapacitated or pass away, the Senate would become Republican controlled for the rest of the 117th Congress!
With the Senate being generally older age than ever before, the danger of such a tragedy is multiplied.
So it is essential for Joe Biden to stop trying to deal with the Republicans, who are recalcitrant, and move ahead on his ambitious agenda.
And with Republicans being very unwilling to cooperate or compromise, hopefully Joe Manchin of West Virginia and Kyrsten Sinema of Arizona might be willing to agree to change the filibuster rule so that action on the Biden agenda can move forward!
Polls find most Republicans say 2020 election was stolen and roughly one-quarter embrace QAnon conspiracies.
