As expected, Senate Democrats — with Eddie Lucio present, not voting — blocked the confirmation of Bryan dentist Don McLeroy as chair of the State Board of Education. At least, everyone seemed to expect it but Lt. Gov. David Dewhurst, who announced after the vote that McLeroy was confirmed, until Senate Parliamentarian Karina Davis leaned in and corrected him. At that point, he apologized and said “it requires two-thirds.”  It sounded as though it was just dawning on him.
