With bomb threats in battleground states and ballot boxes being set on fire, the normalization of such events may signal a worrying trend of voting-motivated violence, said Sonni Waknin, a senior staff attorney at the UCLA Voting Rights Project. Waknin added that as concerns of voting fraud have also gained attention, people have become more active about challenging voters’ registrations and finding ways to disqualify their votes.

In addition, increased administrative barriers around voting – even as small as having to fill out an additional form – discourage people from casting their ballots, she said.

With AP projections continuing to favor Trump, Waknin said she is also concerned about how, if elected president, he could appoint more judges to a U.S. Supreme Court that she believes is already hostile toward voter rights.

“There are two justices … that might retire and that he might appoint,” Waknin said. “That entrenches an anti-voting rights Supreme Court for, probably, the rest of our lifetime.”
