David Primo NYT oped:

One of the largest single disclosures of small-donor information in American history took place on July 31. On that day, the names, addresses, occupations and employers of at least 2.3 million people who contributed money to 2020 Democratic presidential candidates were listed on the internet for all to see. The culprits were not Russian hackers or disgruntled tech workers, but the Democratic presidential candidates and the federal government.

How can this be? The answer, as with all things about campaign finance, is convoluted — but also troubling, as it highlights how transparency in campaign finance can go too far.

Leading (and not so leading) Democratic presidential candidates use ActBlue, an organization that helps Democrats in local, state and federal races raise money with a state-of-the-art online fund-raising infrastructure. ActBlue eliminates the need for campaigns to worry about the technical side of fund-raising and makes it feasible for candidates to raise contributions from donors giving as little as a dollar. (Small donations really matter in the 2020 campaign, as the Democratic Party’s new debate qualification rules include having a sufficient number of unique campaign donors.)

Each time an individual contributes to a presidential candidate using its site, ActBlue collects the donor’s information and then turns around and reports it to the Federal Election Commission — which then puts this information on the internet. Give just one dollar to a candidate through ActBlue and your donation becomes public for the world to see.

This may seem puzzling. Under federal law, candidates must publicly disclose the personal information of only those donors who give them more than $200 in an election cycle. Viewed in this light, ActBlue’s most recent filing, from July 31, makes no sense, as many of the disclosed donors had given tiny amounts well below this threshold.
