That is just not going to happen as any delay will favor the incumbent (Trump). If the Dems feel they are ahead, they will want to seal their victory on Nov 3. If they feel they are behind, they will use Nov 3 to bus every street bum, drug addict and shut-in they can find to the polls.
A delay can only hurt the Dems, especially as it begins to sink in with even the information challenged electorate that Biden is a crook and completely unsuitable for the presidency. The MSM can only hold back these revelations for so long. They can only hide Biden in a basement for so long. Every day that goes by, Biden is losing more votes.
Right now, it's a race against time and they only have two weeks. It's not looking good for them (the Dems).
I hope that you are correct.
