gaslighting
[ˈɡasˌlīdiNG]
NOUN
The practice of psychologically manipulating someone into questioning their own sanity, memory, or powers of reasoning.
The same thing is happening with the Opinion Polls, Trump has been showing to be far ahead of Biden until the Democrats became 100% convinced no Republican was a serious challenger to him, once that happened the polls have started to narrow with a few indicating Biden is now ahead.
This shift to Biden will continue along with fake economic numbers, by Labor Day, the polls will show a neck and neck race with momentum by Biden, this will continue right up to the election.
The polls and economic statistics are designed to manipulate public opinion and shift a small number of people in key states that decide the outcome.
Good point like Biden’s exaggerated speeches and statements.
