"Under the First and Fourteenth Amendments, an election-code provision of this kind must serve a legitimate purpose that is sufficient to warrant the burden it imposes on the right to vote. And under the National Voting Rights Act, an organization has a federal right to conduct a voter-registration drive, collect voter-registration applications, and mail in the applications to a state voter-registration office. But § 97.0575 and Rule 1S-2.042 severely restrict an organization's ability to do this. The statute and rule impose a harsh and impractical 48-hour deadline for an organization to deliver applications to a voterregistration office and effectively prohibit an organization from mailing applications in. And the statute and rule impose burdensome record-keeping and reporting requirements that serve little if any purpose, thus rendering them unconstitutional even to the extent they do not violate the NVRA."
