Mugging for the Cause
Both Atrios and NTodd are running Kerry donation campaigns right now and I support them whole heartedly. While I may not be a card carrying Democrat and have doubts about the validity of the Democratic process as a whole, it's all we've got to work with. So if you really want to get rid of Bush in November, donate to Kerry, the DNC or MoveOn.
Disclosure: I haven't donated yet but I'm in Grad School. So when my next round of loans come in, I'll be dropping some coin in the bucket.
