(CNN) - Hillary Clinton can add three superdelegates to her total. Former New Jersey Governors James Florio and Brendan Byrne were elected their state’s unpledged add-on delegates to the convention Thursday. Unpledged add-on delegates have the same voting rights as “superdelegates” and do not need to vote with the primary or caucus results of their home state.
Florio and Byrne endorsed the New York senator last year, along with current “superdelegate” Governor Jon Corzine. Clinton beat Senator Barack Obama in the New Jersey primary in February 54 – 44 percent.
On Friday, Ohio congresswoman and superdelegate Betty Sutton endorsed the New York senator.
Obama claimed four new superdelegate supporters this week.
