The super PAC founded to urge former secretary of state Hillary Clinton to run for president officially launched Tuesday, complete with a new Web site to help the group ramp up its online fundraising operation.

“We are going to keep up the energy and excitement surrounding her potential candidacy. To succeed, we need to start building an extensive field program — getting neighbors talking to neighbors, organizing on college campuses, and putting together the winning team of supporters that will help Hillary win in 2016," Ready for Hillary PAC Chairwoman Allida Black said in a statement. "Together, let's send a resounding message that America is ready for Hillary. Stand with us today!”

Ready for Hillary PAC is also urging supporters to pledge to help Clinton if she runs for president.

The group said this week that it is gaining more than 1,000 supporters a day and already has more than 100,000. It has also signed up well-known Democratic operatives and former Clinton aides to lead the effort.

Clinton, who stepped down as secretary of state this year, has left the door open to another presidential campaign but has said she doesn't plan to and doesn't believe she will.
