In July of this year, the Democratic Party announced that it had chosen Paul Rivera, a New York political consultant, to prepare a report on why the party lost the 2024 presidential election. On December 18, the Democratic National Chairman, Ken Martin, said that the report has been completed, but it would not be released publicly.
It had been hoped that the Rivera report would say the Democratic Party made a mistake when it attacked the ballot access of Robert F. Kennedy, Jr. The relentless attacks caused Kennedy to drop out of the race and endorse Donald Trump. But whether that point got into the report or not is a mystery.
