A Republican state legislative race in west-central Illinois has become a test of Governor Bruce Rauner's reach.
Back in August, the Illinois Senate took a vote on legislation Gov. Rauner called the worst he'd ever seen. The union-backed bill would allow state labor contract disputes to go to arbitration. Sen. Sam McCann was the only Republican to vote in favor of it.
He says that's the reason he's facing a primary. And not just any primary -- political action committees with ties to Rauner have spent some $2.5 million dollars against McCann.
