The Twitterverse blew up Monday afternoon when Melissa Joan Hart announced that she is backing Mitt Romney and Paul Ryan. The "Sabrina, the Teenage Witch" actress had previously made clear that she was a Republican but had yet to announce an endorsement for the 2012 election.
Joan Hart first alerted followers that she would be taking a political stance later in the day.
She then asked followers about being Republican in Hollywood.
Finally, she publicly endorsed Mitt Romney and Paul Ryan.
Known also for her role as Clarissa in "Clarissa Explains It All," the actress joined the laundry list of celebrities who have made their political affiliations clear in Tuesday's election.
