Rep. Mimi Walters' Orange County race moved to 'toss-up' by election handicapper

"On Thursday, analysts for Larry J. Sabato’s Crystal Ball at the University of Virginia’s Center for Politics moved her race in the 45th Congressional District from “leans Republican” to a “toss-up.”

Kyle Kondik, managing editor of the ratings publisher, cited the fact that Walters received just over half of the vote share in her district during the June 5 primary, a marked decrease from previous years. "
