Ron Donatucci has a lot of titles: Philadelphia Register of Wills, 26th Democratic ward leader and presidential super-delegate.

Donatucci was an early arrival today for the noon meeting of the Democratic City Committee, where ward leaders will discuss whether to endorse U.S. senators Hillary Clinton or Barack Obama.  Rumor is the ward leaders will leave the endorsement open.

PhillyClout's Catherine Lucey is staking out the party headquarters on Walnut Street.  Here's what Donatucci, a Clinton supporter, told her just a few minutes ago: "I believe we're going to do an open primary. For party unity, I think it's best to keep an open primary."

About 10 Obama supporters were on scene, chanting and waving signs.  Former President Bill Clinton is expected to arrive soon to make a pitch for his wife.
