Wondering how President Obama is doing with his base? You could check with the $35,000-a-head donors at his 50th birthday celebration at the Aragon Wednesday night. Or you could check in Thursday morning with his original base, the members of the Developing Communities Project  in Roseland, where Obama was a community organizer from 1985 to 1988.
DCP members will be celebrating the day with a birthday cake. They;ll also get a progress report on the Red Line Extenstion, which the group has advocated for many years  (CTA is completing an environmental impact study). And kids from DCP’s summer organizing camp will give a presentation on their transit projects.
The party starts at 11 a.m. on Thursday, August 4, at Lilydale First Baptist Church, 649 W. 113th.
