"It's very clear you have to engage the public and say: You have to vote no on 74, no on 75, no on 76, no on 77. Those are the issues that Arnold pushing. And those are reactionary, Republican initiatives"

This quote by Warren Beatty is referring to the requirement for the general public to do something about it and vote against initiatives proposed by Arnold Schwarzenegger.

He is stressing the value of engaging the public in the voting process and making sure they are aware of the initiatives that Arnold is pressing. Beatty is motivating the public to take a stand against these efforts and to make their voices heard. He is emphasizing the importance of voting and making certain that the general public is notified about the initiatives that Arnold is proposing. By voting "no" on these efforts, the general public can make certain that their voices are heard and that their opinions are taken into consideration.
