I would tend to agree, but voting is just the first rung of what you might think of as a ladder of commitment:

Voting Organizing others Donating money to fund full-time campaigners Volunteering for leadership positions/running for office

Each step on the ladder requires more commitment, and will therefore be taken by fewer people. But to succeed, a movement needs all of them.

If you vote, and nothing changes, and you're asking what comes next, maybe you're ready to move to the next rung. Start a meetup in your community. Give to the EFF or the ACLU. Run for office yourself, or identify a good person who should be running and help them do so.
