Rachel Silberstein is reporting for Capitol Confidential over the course of two days, eight Republican county chairs have changed their endorsements from state Sen. John DeFrancisco to his opponent, Dutchess County Executive Marc Molinaro, for the GOP gubernatorial nomination. Party leaders in Oswego and Tompkins counties announced April 24 they had changed their endorsements. Chairs in Madison, Oneida, Jefferson, Broom, Chenango and Delaware counties made the switch the following day.

DeFrancisco said this week that he would not primary the party's choice, if Molinaro prevails at the convention. Read the full story at Capitol Confidential, a Times Union blog.
