Pundits add Fischer won't be easy to beat. In her competitive Republican primary, Fischer put nearly 50,000 miles on her own car campaigning across the state.
"Fischer has not spent a ton of money. Instead she has spent a lot more time focusing on a ground game. She spends most of her time with small groups," Adkins says. "You don't see her on TV on the news quite as much as you would expect to see someone who is leading. Their campaign has been quiet. In some respects, it has to be. They want to sit on their lead."
