Clean Elections USA is trying to mobilize thousands of volunteers to collect evidence for True the Vote and a conservative sheriffs' group, internal communications show

The movement to try to catch illegal voting at ballot drop boxes in Arizona, which is spurring complaints and lawsuits alleging voter intimidation, is not the local grassroots effort it appears to be.

The drop box watchers are part of a coordinated fast-growing national effort with thousands of volunteers who say they want to help try to collect evidence of people illegally depositing others' ballots during the midterm election, according to a Votebeat review of internal discussions among group organizers, internal contact lists, and posts and videos on right-wing media sites.
