Even Barr and some on Trump's staff has admitted that it is over, Biden won, and there is no evidence of enough supposed "fraud" to change the election results. On top of that, Trump said even months ago he would not accept the results if he supposedly lost. Now what he is doing is to basically stage a coup, and Michael Flynn is now pushing that. Is this what we really want? If that were to work out that way, do we really want to become the "Fascist States of America"?
But the greater danger is that conspiracy theories like this actually have the effect of undermining our democracy. Already, we're are hearing some people say they will never vote again. This is not good because democracy is based on a large element of trust, thus to destroy trust is to destroy democracy in the long run.
The real contested election was Bush v Gore, and yet when the split SCOTUS decision along party lines gave it to Bush. If any party were to have a full right to complain it would have been the Dems back then because the decision was strictly along partisan lines. But Gore left with dignity.
