Not a single major 2020 presidential contender is disclosing the names or activities of bundlers of campaign donations. That’s the latest news from the Center for Responsive Politics.

The only candidate to make even a half-hearted attempt to do so is South Bend, Indiana, Mayor Pete Buttigieg, who stopped updating his list of bundlers in April. Other Democratic candidates, including Kamala Harris and Amy Klobuchar, have promised to do so but haven’t followed through, while still others claim to have no bundlers at all, including Andrew Yang and Tim Ryan, or no “official” bundler program, such as Bernie Sanders and Elizabeth Warren.
