Not worried? Why would that be, humm? Surely nothing to do with expanded ballot drop boxes, or open ballots?
Only people confident of winning the next election would not be concerned. There will be no Red Wave, rather it will be a repeat of 2020 and a Blue Tsunami. With elected GOPers everywhere proclaiming it a free and fair election ...
Keep in mind that the GOP picked up seats in the House in 2020 because the fraud machine cannot affect every congressional district.
The fraud machine works in blue precincts and affects statewide races (governor, senator, attorney general, president)
That is why you saw the 2020 results of Democrats picking up seats in the Senate and winning the White House, but losing seats in the House of Representatives.
