In politics and mind manipulation it is said until you say the same thing 500 times you haven't said anything at all. Denialism of elections has lost its edge and is dulled by the capital and family attacks among non-fanatics. The investigations only helped shape the minds of the left.
Denialism started up back during the W Bush election that Bush in reality lost. Bush's lawyers successfully blocked the initial count in Florida. The Supreme Court aided the sham.
Denialism is now over used and abused in America.

The Putin method is to win elections by the people who count votes, not the people who vote. Arrest, poison or shoot all your opponents.
