It was always going to get ugly in the final weeks.

With Sanders surging in the polls and racking up progressive endorsements leading up to the first primaries, and both rival candidates and the wider Democratic establishment openly admitting their nervousness about his very good chances of winning, the likelihood was high that Sanders was going to face a torrent of negativity.

What may be surprising is who’s joining in — Elizabeth Warren. Some mild jabs late last year aside, the two candidates have mostly avoided criticizing each other directly. In fact, last Democratic debate, after Warren’s attack on Pete Buttigieg’s wine cave fundraiser backfired, with both he and the media criticizing Warren for having attended similar big money fundraisers in the past, Sanders came to her defense, hitting Buttigieg and Joe Biden (and, pointedly, not Warren) for their prolific fundraising from billionaires.
