Politicians, especially Democrats, have repeatedly claimed there is no evidence of voter fraud.  There may not be any because there has not been a serious investigation of voter fraud.  That could change with Trump’s Voter Fraud Panel investigation.  The push back from states strongly suggests voter fraud is common and they have done little or nothing to stop it.  That, I believe, is what they are trying to hide. Since most or all of the information requested by the Panel is public, what other reasonable explanation can there be?
