As early voting starts in Georgia’s governor race, businessman Rick Jackson is holding his edge over fellow frontrunner Lt. Gov. Burt Jones in the latest GOP primary poll.

An InsiderAdvantage survey from late April has Jackson at 32% support among likely GOP primary voters. After Jackson, 25% of the 800 respondents said they would support Jones, and 11% said they’d back Georgia Secretary of State Brad Raffensperger. Georgia Attorney General Chris Carr polled at 6%, while 23% of respondents were undecided.
