If the voting machines and ballot counting are controlled by Demonicrats in those seven swing states, it doesn’t matter what the polls claim.
You’re wrong. Democrats only cheat when the polls are within the margin of error. If Trump polls 8 points ahead of Biden, and Biden wins people would demand a recount. It’s why some democrat precincts don’t turn their ballot boxes in until after midnight - they’re waiting to see how many votes need to be added. Too many and it calls attention to the fraud - too few and ‘their guy’ loses.
