I just read an article on Jezebel about this- they were against it, since, as they put it: "The problem with this idea is that Obama forewent public financing on the basis of relying on donors — big and small — to continue giving him money. If people give the $5 or $10 to PPFA instead and send cards to McCain's office, you're just notifying him how much money Obama is losing. Heck, I wouldn't put it past a Republican operative for starting the chain, especially since it doesn't encourage donations to PPFA's PAC, which can spend the money to run ads about the candidates/reproductive rights, but to the organization itself, which cannot. Please be careful about forwarding this along. If something like this really went viral, it could do a lot of damage."

I don't know if I agree with what they say- there's no guarantee that giving money to PP means you can't donate to Obama, but I thought I would put it out there, since I think they have a little bit of a point.
