In several primaries this spring, Democratic voters have embraced mail ballots in far larger numbers than Republicans during a campaign season defined by the coronavirus pandemic. And when they urge their supporters to vote by mail, GOP campaigns around the country are hearing from more and more Republican voters who say they do not trust absentee ballots, according to multiple strategists. In one particularly vivid example, a group of Michigan voters held a public burning of their absentee ballot applications last month.

The growing Republican antagonism toward voting by mail comes even as the Trump campaign is launching a major absentee-ballot program in every competitive state, according to multiple campaign advisers — a delicate balancing act, considering what one strategist described as the president’s “imprecision” on the subject.

“It’s very concerning for Republicans,” said a top party operative, who like several others interviewed spoke on the condition of anonymity to avoid drawing Trump’s ire. “I guarantee our Republican Senate candidates are having it drilled into them that they cannot accept this. They have to have sophisticated mail programs. If we don’t adapt, we won’t win.”…

“It does reduce the likelihood of Republicans embracing this process,” said a senior GOP strategist. “Especially for older, more rural voters, that could be important for Republicans getting out the vote in 2020. I don’t want ‘I will not vote by mail’ to become a political statement. But it may be too late.”
