Removing support for people who endorse it. Before you vote for anyone study their actions and history. Ignore their words as the actions are what truly matter.
If they are already in office if you can find a reason and way to recall them DO IT. If you can't then plan to replace them.
Now I'd like to see no government, but I believe we must do things in stages... minimizing it to as little as we can get it is a step in the right direction as far as I am concerned.
