“Warren’s charge that the Democratic primary was ‘rigged’ says more about 2020 than 2016” – the commentary is written by Annie Linskey & co-author.
The real bone of contention here seems to be about how primary Democratic campaigns are going to be funded, going forward. The DNC has allowed big-donor supported candidates to get funding in primary campaigns. Without the DNC vehicle, big-donor candidates would be hamstrung in the primaries by the $2,700 personal contribution limits.
This is a fight over who should the Democratic party represent: small contributors, or very wealthy contributors.
It’s not something that the Globe commentary is interested in mentioning.
