It'll only be the new normal if it works, though it certainly highlights the danger to democracy that Trump and ilk have been when any unfavorable result will be declared as rigged.

I can only hope that Biden has the new congress enact laws to codify many of the norms that have been trampled upon by Trump. An honor system doesn't work with a thoroughly dishonorable person at the top.
Biden will need the courage to actually ask for legislation that can limit executive power, perhaps even a constitutional amendment.
