Are You Part of a Political Organization?
If so, consider convincing that organization to hold a public meeting to address healthcare concerns in your local area. Publicize the crap out of it. Promise answers about what the Republican healthcare bill means to local citizens. Arrange for speakers and schedule it in a place large enough to hold a crowd.
If you have a Republican House member, invite him or her to show up and explain why he or she voted for this bill. If that person won't come (almost certain), find Democratic candidates to make a presentation.
At this meeting, go through the bill, point by point and show what its impact will be on average people. Compare it to the current healthcare environment.
Such a meeting will take planning, and needs an organization to run it. Don't call it a protest. Call it something else. Make it an educational forum.
