Democrat Danica Roem will become the first openly transgender person to be elected and serve as a state legislator, after ousting one of the country’s most anti-LGBT lawmakers in a closely watched Virginia House of Delegates race Tuesday.

Her opponent, GOP Delegate Bob Marshall, has served in the state legislature for 26 years. He’s known for writing Virginia’s constitutional amendment banning gay marriage. This year he introduced a “bathroom bill”—intended to prohibit transgender individuals from using the restroom matching their gender identity; his own party killed that proposal in committee.
