As we approach Pennsylvania's May 16 primary election, the seven Democratic candidates for Philadelphia district attorney all appear to have a shot at a block of voters.

Some have money. Two have independent groups running TV ads for them. Others have unions, politicians, newspapers, advocacy groups or ward leaders backing them.

In part because you can learn something about people from who their friends are, I've compiled the following list of endorsements in the race. It's representative, not comprehensive. I've tried to include the most significant endorsements, and I will try to update as the campaign unfolds.

Where candidates claim the support of specific Democratic ward organizations in the city, I've included them in the list, because ward leaders matter in a low-turnout election.

In most cases, I haven't independently verified the information with the wards. As I write, two candidates claim Ward 66A, and I'm hoping to reach ward leader Shawn Dillion to clear that up.

UPDATE:  A far more comprehensive look at which candidates have ward support is available in a piece by Max Marin of the Philadelphia Weekly. It shows several candidates have siginficant backing from ward leaders. None have anything close to a majority.

Republican candidate Beth Grossman has no competition in the GOP primary.
