Sen. Campfield is not saying Richard Montgomery lost because he didn't support his bills, but "some people" are saying that:

The upset of the night was Dale Carr over Richard Montgomery by 77 votes. Richard was a powerful chairman who had the money and the Governor come in for him. It wasn't enough. Some say it was being the one Republican vote against my Classroom protection act in committee. Others say it was his vote against electing school superintendents (Another bill of mine). I am not going to say that.
