Dan Winslow, a Republican state legislator in his second term, has resigned from the Massachusetts House, effective September 29. Besides being a state legislator, he was general counsel to Americans Elect from its founding until it dissolved.
He had introduced two bills in the Massachusetts legislature earlier this year to improve ballot access. But the legislature never held a hearing on either one. He also ran for U.S. Senate in the special election earlier this year, but he did not win the Republican primary.
See this story, which explains that Winslow resigned from the legislature because he has a new job with a salary that will substantially increase his income.
