Expect more, and also expect a whole raft of state initiative measures to be put on the November ballot. This is similar to 2004, when it was part of a national Republican campaign strategy to place initiatives against same-sex marriage on state ballots across the country to mobilize the right-wing base. While the Party wanted the measures to pass on their own "merits," the purpose went beyond that. By engaging and mobilizing the bigotry of their base, they maximized turnout to ensure that George Bush was re-elected as President.
The strategy is now being repeated, substituting transgender-bashing for the anti-same-sex-marriage issue. Transgender folks are a convenient political punching bag, and it's going to get worse before it gets better.
