Maybe Melissa Joan Hart, Stacey Dash and Shannen Doherty should think about forming their own Super PAC?

After all, all three '90s stars are outspoken about their support for conservative politicians. On Monday -- just a few weeks after Clueless alum Dash took heat for tweeting that she's voting for Mitt Romney -- the Clarissa Explains It All actress did the exact same thing.

At first, Hart, 36, cautioned that a political tweet or two was imminent.

"Warning: I may get political today but just stating my feelings, not intending to sway anyone or get into arguments #maylosefollowers," she wrote.

A few hours later, she did just that: she got political.

"Finish this sentence for me . . . Being a republican in Hollywood is like being . . . ???? #election2012" Hart tweeted.

One minute after that, Hart quit playing coy and came out with it.

"Can't get too political in only 140 [characters] but for those asking, I'm voting #RomneyRyan," Hart told her 257,000 followers.

Former 90210 star Doherty, for her part, hasn't weighed in on who she's supporting on Election Day, though she has spoken out before about her right-leaning views.

"I realize that the majority of people in the entertainment business happen to be Democrats," she has said. "I have no problem with that. And they should have no problem with the fact that I'm a Republican."
