Although perhaps the simplest reality is that the means to intimidate by mimicking the Proud Boys is based on the fact that the Proud Boys are an intimidating group.I believe the likelihood that some asshole wanted to intimidate voters, and used a fake Proud Boys email address to better evoke fear, is higher than the likelihood that a left-winger sent fake intimidating emails to other left-wingers to make them more likely to vote against the way the letters told them to, yes. Because the latter involves loads of extra steps and presumptuous leaps.
