What else can I do to make clear my support for health care reform to elected officials?

I decided this morning after reading the details of the Administration potentially folding on a public option, that I had to do something to try to counter the loud voice of ignorance.

So, far I (and my husband) have sent emails to the White House asking the President not to cave on this issue and to reconsider the provision about negotiating with drug companies.

My sister told me about this group, Mad as Hell Doctors.

What else can I do? Especially that would get to more people and get them to do something? Have you done anything?
