Natalie Portman is taking to the Internet for a little political advocacy. In a new, 30-second public-service announcement, the actress, 26, encourages people to get out and vote. "Voting's how our democracy works," she says.

Non-partisan – and unaffiliated with the presidential election – Portman's spot focuses on the importance of participating in the democratic process. "To vote is to express yourself," she says.

Tethered to a new documentary Chicago 10, about protesters at the 1968 Democratic National Convention, Portman's message also directs viewers to Takepart, a forum that allows for the discussion of current political issues of concern.
