biden before the steal vs. biden after: total reversal of position--and Democrats have no problem with it

Before the 2020 presidential election bidenfail said every covid death was Trump's fault.  After all, Trump wuz duh president, so obviously it had to be his fault, eh?

After the steal, bidenfail changed his tune, radically.  "There's no federal solution.  This problem must be solved at the state level."  The amusing thing is, Democrats don't have any trouble believing both bidenfail positions--at the same time.
