Democrat, nonprofit leader Melissa Vine launches campaign for Iowa’s 3rd House district

The Democratic nomination in Iowa’s third U.S. House district will be contested, with the formal entry of a second candidate into the race Wednesday.

Melissa Vine, a Des Moines-based nonprofit leader and small business owner, is jumping in to challenge U.S. Rep. Zach Nunn. She’ll face a primary opponent in former U.S. Department of Agriculture and veteran Lanon Baccam, who announced his candidacy last week.
