I have no idea what DJTs mental health outlook is....but, it seems unusually petty to be constantly obsessed with legitimizing his inauguration attendance & vote margins. Reporters have been asking all along for evidence of the fraud & raising the question if he believes it so strongly and it's so wide-spread, why no investigation has been launched to establish the source and safeguard our process. The Pew study the administration has cited that Trump read from '08 was on administrative registration inaccuracies & not a study of fraud. Even the author of the study has said no correlation and zero fraud indicated.
By all means if there is credible evidence that widespread voter fraud was committed, let's see the evidence & open an investigation.
At this point with these evidence-less claims, we don't need the Russians to destabilize our system....
