Trump is paying for poling that shows the race being far more competitive than it is.  This is going to drive Dem turnout, but he knows he's going to lose the vote.  

He needs the numbers to be close so when he loses multiple battleground states can declare their counted votes invalid and push the results to the state house where Trump will win the state, and the electors.  To be clear, the wild level of corruption that occurred in the 2020 election and the absolute lack of consequence for most of the higher ranking political figures in the movement meant that this was bound to happen a second time.
