Likely aware of the strong backlash other celebrity Romney supporters have earned on Twitter after sharing their vote, Hart earlier in the day tweeted a warning that she might “get political.” She also nodded to the fact that big-name stars rarely come out in favor of the Republican ticket.

Although President Obama has plenty of star power on his side, Romney’s show business supporters number in the lower digits. Kid Rock, Meat Loaf, several country singers including Rodney Atkins and Five for Fighting’s John Ondrasik have hit the campaign trail for Romney this cycle. Actresses Lindsay Lohan and Stacey Dash also voiced support, and both received strong pushback for voicing their choice.

Hart is best known as the star of long-running shows "Clarissa Explains It All" and "Sabrina, the Teenage Witch," and currently stars on ABC Family’s "Melissa & Joey."

Celebrities on both sides of the aisle have been urging their fans to vote on Monday.
