I am biased, but my opinion is based on the absence of any evidence, and the lack of credibility on display by the Trump legal team, specifically Rudy Giuliani, who made a complete fool of himself outside of a landscaping business in Philadelphia on Saturday morning. The burden of proof rests with those who are alleging fraudulent activity, and to this point, they have not met their burden.
None of the anecdotal evidence you are discussing has been verified. Some of those people making these allegations (such as Daryl Brooks of Trenton, New Jersey - Giuliani's sex offender witness from the landscaping press conference, have already been discredited).
Some people are signing affidavits. Some people such as Richard Hopkins from Erie, Pennsylvania. He is the USPS driver who has now recanted his allegations. Just because you sign an affidavit, doesn't mean you are telling the truth. Richard Hopkins obviously wasn't. I have more proof that the people making allegations of fraud are lying... than you have that they are telling the truth. I just named two of the proven liars: Daryl Brooks of Trenton, New Jersey and Richard Hopkins of Erie, Pennsylvania. Google them if you don't believe me: Daryl Brooks of Trenton, New Jersey (Rudy Giuliiani's sex offender) and Richard Hopkins of Erie, Pennsylvania.
By the way, Rudy Giuliani's press conference from Saturday is the most farcical display of comedy I've ever seen. If he is the best Trump can do for legal counsel? Then there is no point in not conceding. Rudy Giuliani is a goofball loser.
