Siobhan "Sam" Bennett, according to her NWPC bio, "is the Statewide Director/CEO of Properties of Merit of PA, Inc., a non-profit organization Sam established to spur citizen involvement". Her bio there reads like that of a community activist. I was impressed with her FireDogLake chat last year. She's articulate, and she's for the things we want, like universal health care and ending the Iraq War. On the latter subject, she was, along with Donna Edwards, a cosponsor of Darcy Burner's recently announced Responsible Plan to End the War in Iraq.
My personal reason for supporting her is that she's trying to represent the House district I grew up in, PA-15, which is now represented by Charles Dent. Dent while maintaining the fiction that he's independent, has voted with President Bush on nearly every key piece of legislation. If you want the war in Iraq to go on forever, and for there to be no restoration of habeas corpus, then voting for Charles Dent is a good idea. If you're not, just about anyone would have to be an improvement. Sam Bennett strikes me as much more than that.
