Sounds like it is time for a concentrated and organized effort to rid the state of Sen. Harry Marsh. It may surprise you what a group of dedicated people going door to door, all concentrated in one district, in the last few weeks before an election can accomplish. Remind people that he violated senate rules to advance his personal agenda.
Then, the day after the election that removes him from office, hold a press conference and take credit for booting him because of his stance on gun control. It only takes a few of these to change the whole attitude of a state legislature.
