Ideas to get involved

I've written to my representatives in Washington to oppose the frightening changes to our goverment and I've donated money to organizations who are lobbying against this administration. I'm game to attend a protest, but I only ever seem to hear about them after the fact. I'm located in Nevada and I'm registered as Republican so that I can have a voice in the Republican primaries. What else can I do? I have time to write, call, or attend in person events and I want to do more.
