Conservative groups are challenging voter registrations across the U.S. under the guise of cleaning voter rolls, sparking concerns about election integrity. Tactics include door-knocking campaigns and using software to identify questionable registrations. Efforts led by Republican officials are seen by Democrats as attempts to sow doubt in the 2024 election results. Initiatives like 'Soles to the Rolls' in Michigan aim to scrutinize voter lists, potentially affecting voter eligibility. The push to update voter lists is viewed differently, with conservatives emphasizing integrity and Democrats wary of its impact on election credibility.
