“Voting is one of the most important civic duties we have, ensuring that issues that impact us the most are top of mind for the politicians that represent us,” he wrote.
“The impact voting has on us is tremendous, shaping the way our communities work in ways that are often overlooked.”
Other famous faces posting online included singers Idina Menzel, Katy Perry , Lizzo and Selena Gomez, who wrote: “Your voice matters!” on her Instagram story.

Perry added: “I am voting for a myriad of reasons (see the news) but in particular because Los Angeles is a hot mess atm.”
Ahead of the polls closing actors Mark Ruffalo, Halle Berry and Viola Davis also urged fans to submit their ballots.

“Make sure your voice is heard & head to the polls to cast your vote. Remember you have the power, and we need you.”
“Hey everybody… if you haven’t voted already, make your voice HEARD tomorrow!” Berry said, while Davis branded herself a “proud voter”.
