He signed a bill into law in Ohio this year that forced young girls and women to carry the products of rape and incest to term. He's also a big proponent of gay conversion "therapies" and opposes marriage equality and same-sex adoption, as well as voted against efforts to prohibit discrimination based on sexual orientation.
That's just the tip of the iceberg. He's nothing but another ugly face for the bigots and morons of his party to fawn over.
