Pat Boone can be seen in a two-minute YouTube video endorsing the proposed constitutional amendment on voting that will be on the Minnesota ballot in November.
Boone, a singer and actor who came to prominence in the 1950s, has been a political supporter of many conservative and religious issues.
The video was produced by Voter ID for Minnesota, a group supporting passage of the amendment, which would require voters to show a government-issued ID before casting a ballot, and make other changes to voting procedures.
