Speakup is nice and all, but it doesn't come close to what you need to do to effect change.
1. Run yourself;
2. Run a candidate whom you agree with
3. Support a candidate with whom you agree with
4. Support via monetary contribution
5. Support via petitioning, canvassing, lit drops, in-kind contributions, handing out lit at parades, helping pay for materials, running fundraisers, publicizing fundraisers, GOTV efforts in the days leading up to election day.
6. Get the word out and convince people why your POV is better than the other guy's.
