Emma Watson may not be eligible to vote on Nov. 8, but that doesn't mean she doesn't have an opinion.

The British actress -- who is an outspoken feminist and UN Women Goodwill Ambassador -- took to Twitter on Tuesday to share her thoughts on the upcoming U.S. presidential election and encourage those able to vote to use their power.

"At times, politics may seem disillusioning, filled with rhetoric and smokescreens," Watson began her essay. "However, regardless of our personal beliefs, it can't be denied that the result of the upcoming US presidential election will have ripple effects around the world and impact, in one way or another, the lives of millions and millions of people."

"It has been excruciating to sit on the sidelines in the months leading up to this election," she continued, adding that America has been her "second home." "Goodness, I wish I could cast a vote."

"The next president will be able to make decisions about women, about their bodies, about how they are treated at work, on university campuses and at school, about how men treat women and about their rights as citizens," she wrote. "These decisions affect how young people form their ideas of gender. These decisions will affect whether we believe equality is an idea that matters."

The "Harry Potter" star goes on to urge women to head to the polls, mentioning that 70 million women cast ballots in the last American election, as compared to 60 million men. "You have real power to decide the future of generations to come," she stated.

This isn't the first time the actress has spoken out on gender equality. In fact, Watson name dropped Hillary Clinton for her support of the UN Women's HeForShe initiative last year.

"It is my belief that there is a greater understanding than ever that women need to be equal participants in our homes, in our societies, in our governments and in our work places," Watson said during her speech at the World Economic Forum in Davos, Switzerland, in January 2015. "And they know that the world is being held back in every way because they are not."
