A Republican Super PAC is already working to keep Hillary Clinton from possibly winning the White House in 2016.  The PAC America Rising has launched the fundraising website StopHillary2016.org to counter growing support for another potential Hillary Clinton presidential run.  The PAC's executive director is Matt Rhoades, who managed Mitt Romney's 2012 presidential campaign.  The group is sending emails to donors that explain the PAC's goal is, "to prevent Americans from ever having to see another Clinton in the White House or suffer through 12 years of Democrat rule."
