In the Indiana gubernatorial race, a new poll shows Republican Mike Pence leading Democrat John Gregg by an 18-point margin.The Indiana Chamber of Commerce released the survey Thursday showing that among 600 likely voters, Pence has 50 percent while Gregg is being backed by 32 percent in the fall election. Polling also shows Libertarian candidate Rupert Boneham with about 3 percent support, and that 15 percent of Hoosier voters are still undecided.Pence campaign spokeswoman Christy Denault says they haven’t focused on the poll numbers, but instead on touting their platform."Mike has a vision for how to make this a state that works, we’re focused on jobs and education," she says. "We have a whole slate of policy rollouts already scheduled and we’re going to keep rolling out our ideas so that the people of Indiana get an idea who Mike Pence is and what he will do should he become governor of this great state."Gregg launched his first ad of the general election this week highlighting his small town roots, but Pence has released six commercials that have been biographical and explained his proposals.Gregg is a former House speaker, but he has struggled to keep pace with Pence’s fundraising and advertisement. The Gregg campaign launched its first TV ad this week, while Pence is on his sixth of the general election.But Gregg campaign spokesman Daniel Altman tells WFPL they are still optimistic about the fall campagin."Voters are just now starting to learn things about Pence like despite the fact that he’s been in Congress for the last 12 years he hasn’t passed a single bill once. I think the more voters learn about him and the more voters learn about John Gregg, the more you are going to see voters coming towards the Gregg/Simpson ticket ,” he says.
