Democracy is 2 lions and a sheep voting on what’s for dinner. US is not a democracy. We are a constitutional republic. The word “democracy” does not appear in the declaration, constitution or bill of rights.
The 7 million live in the peoples republics of California/New York. Discount those 2 states and trump won 2020 popular vote by 1 million.
Mail in and drop box fraud are impossible to prove. In person voting and video can match number of people who voted with the ballot count. The fraud if it exists would be in the battleground states.
