The fake polls are there to cover the fake absentee and mail in ballots. The voter fraud would be too obvious if Dems were losing by 20% in the polls and they would have a 5% win on Election Day in an off-year election.
The GOP better not be too lazy to check voter totals at the precinct level and be on the lookout for double-voting by absentee or mail-in ballots. Dozens of ballots sent to one address should be a tip-off to even the least interested election officials, but not if they’re Democrats.
Discovering that 110% of registered voters in an area voted and all of them voted Democrat does the Republicans no good at all. Those votes will not be thrown out. They will count, no matter how open the cheating. Some Democrat ops may eventually be fined. One or two may even go to jail but they will be rewarded handsomely by their Party and it is all worth it to them.
