Melissa Joan Hart, the actress most well known for playing "Sabrina, the Teenage Witch," told HuffPost Live that, because she tweeted her support of Mitt Romney, she was overwhelmed with hateful insults in 2012.

"I got called every name in the book. And told I was, you know, they hope I die, and that they hope my children are gay which was, somehow, supposed to be some kind of punishment," Hart said.

She said people called her names she wouldn't say on the program. "The hate was really unbelievable, that I got just for saying that simple tweet."

On Nov. 5, 2012, Hart tweeted that she planned to vote for the Romney-Ryan ticket. It read:

"Can't get too political in only 140 chac but for those asking, I'm voting #RomneyRyan."

The actress, who has not kept her political affiliation or fiscally conservative views a secret, told Sean Hannity and viewers of his Fox News program on Nov. 13, 2012, that there is a blacklist in Hollywood against conservatives.

She was on HuffPost Live promoting her new book, "Melissa Explains It All," which was released Oct. 29.
