Madison County District Attorney Rob Broussard says he won't pursue crossover voters in this year's Republican senate primary unless "somebody puts an investigative file in our office" that he can review and take to a grand jury. Broussard took the position in an interview with AL.com news partner WHNT News 19. See the interview below.

Alabama Secretary of State John Merrill said in October names of voters who crossed party lines to vote in last month's Republican Senate runoff would be turned over to the state's district attorneys. His office has identified 674 such voters, Merrill said, and 63 are in Madison County. Voting for one party in a primary and knowingly crossing over to vote in another party's runoff is a Class C felony.

Merrill said he would turn the voters' names over to prosecutors for investigation and possible prosecution. But Broussard told WHNT that, "Until somebody puts an investigative file in our office that we can review and put to a grand jury, we're not doing anything with it because we don't have anything."

Even if investigations were conducted, an attorney interviewed by WHNT said prosecution would be difficult. "To prove intent, the person would pretty much have to confess and say, 'Yeah, I voted in the primary for the Democrat, and I voted in the runoff for the Republican because I wanted this Republican to run against this Democrat,'" attorney Mark McDaniel said.
