While many voters remain undecided on who to support in the crowded 2020 presidential field, Democratic donors are already reaching into their pockets to support their favorite candidates. In a review of the most recent quarterly filing with the Federal Election Commission, along with the help of GovPredict, Jewish Insider found several donors who have maxed out their contributions to candidates they are backing, donating the maximum amount of $2,800. 

Other notable contributions revealed in the FEC filings include former Secretary of Defense Chuck Hagel’s $2,800 to the campaign of former Vice President Joe Biden, former National Security Advisor Susan Rice’s $2,800 gift to Sen.
