The impending retirement of Bill Callegari, announced today on Robert Miller’s blog, follows those recently announced by Rob Orr and Tryon Lewis. This means three more members of Joe Straus’s team will have left the Legislature by the time the next regular session begins, leaving vacancies in the membership that could impact Straus’s ability to be re-elected as speaker. The likelihood of a conservative jihad against Straus loyalists, as has occurred in each of the sessions since Straus took the gavel in 2009, must be taken seriously by the Straus forces, as Tea Party fervor could sweep the state, as it did in 2010—a year when Democrats lost every contested race.  There is a distinct possibility of another conservative supermajority in 2015.
