A GOP super PAC wants its backers to "slap" Hillary Clinton in an online game, and Democrats and Republicans alike are condemning it.

The Hillary Project, one among a handful of anti-Hillary Clinton PACs and super PACs to crop up this year, has launched an online game encouraging visitors to "slap" an image of Clinton across the face. Buttons allow visitors to play audio of Clinton speaking, then slap her mid-stream.

The game mimics a "Slap Palin" game launched by a fringe group in 2008 and aimed at then-vice presidential candidate Sarah Palin.

Democrats have strongly criticized the promotion of simulated violence against the most prominent female Democratic politician.

The Republican National Committee said on Monday that the game is "in poor taste," after a Democratic group released a petition calling on the RNC to condemn it.

"Clearly any game encouraging people to slap anyone is in poor taste. It was when the Democrats used Sarah Palin as the target and it is now with Hillary Clinton," RNC spokeswoman Kirstan Kukowski told ABC News, adding a few digs at Democrats. "From Bob Filner to Anthony Weiner and Eliot Spitzer, Democrats should look at their own actions, candidates and elected officials before pointing fingers."

Filner, the mayor of San Diego, has been accused of sexually harassing multiple women. Last week, Sen. Barbara Boxer, D-Calif., called on him to step down.

Earlier on Monday, the Democratic opposition research super PAC American Bridge has launched an online petition calling on the Republican National Committee to condemn The Hillary Project and its game.

"Violence against women isn't a game. Enough is enough. If leading GOP groups are going to stoop this low, the RNC needs to speak out," former Maryland lieutenant governor Kathleen Kennedy Townsend said in an American Bridge e-mail to supporters, which the group sent out today announcing the petition.

The game, and the criticism, is the latest development in an ongoing drama over Clinton's widely anticipated, yet nonexistent, campaign for president in 2016. Clinton has not said whether or not she plans to run, but a Democratic super PAC has formed to promote her as a candidate, and the Republican National Committee has feuded with CNN and NBC over planned TV programming on Clinton's life.
