Clinton had the same issue. No one went to her rally. There was no way she had that many votes.
Biden did worse and somehow he had the highest record number of votes. Har har.
Remember the Democratic primary in Iowa? They failed with their voting app and had all sort of glitches that pushed Biden to win the nomination.
Hillary probably got more real votes than Biden because she was female i.e. first female president. She conceded yes because we saw the same algorithm like behaviour in the 2016 results, because trump got about 30m votes than they were expecting. Although, they did have the audacity to fabricate unrelated allegations of election fraud and whine about the election being stolen. This time they had more dominion machines and ballot dumps
I met “hil-dogs”(disgruntled divorced 50-60 yr old women still pissed at their ex-husband) on connecting flights so I knew she had some real support.
