In early July 2020, the Biden campaign released a 110-page document containing what is perhaps the most comprehensive list of Democrat party policy ambitions. The document was titled BIDEN-SANDERS UNITY TASK FORCE RECOMMENDATIONS (yes, they titled it in all capitals). The term “unity” is in reference to the objective of unifying the Bernie Sanders-wing of the Democrat party with Biden’s campaign.
The document is worth reading in order to obtain a broad understanding of the policies that the Democrat party is pursuing as well as to get to know more about many existing public assistance programs that you may not have known about.
