Ready for Hillary, the super PAC laying the groundwork for Hillary Rodham Clinton's potential 2016 presidential campaign, has called a meeting of its top national donors to discuss its strategy following the November midterm elections.

The super PAC has invited members of its National Finance Council to a daylong summit in New York City on Nov. 21 to a discussion of the group's next steps as it prepares for Clinton's likely entry into the presidential race.

Clinton, a former secretary of state who would be the overwhelming favorite for the Democratic nomination, has said she will make her decision about the 2016 race early next year. Meanwhile, Ready for Hillary has been building a grassroots infrastructure on her behalf and has signed up more than 2.5 million supporters.

Craig Smith, a senior adviser to Ready for Hillary and a longtime political adviser to former President Bill Clinton, invited top donors to the summit in an e-mail sent Monday night and obtained by The Washington Post.

"This meeting will be the premier opportunity to hear from those individuals who will be shaping the next few years in our Nation’s politics and a chance for Finance Council Members to come together and meet one another while we wait to hear what Hillary will decide," Smith wrote.

At least 222 donors have signed up as co-chairs of Ready for Hillary's National Finance Council — a commitment that requires donating or raising $25,000 each, according to a membership list obtained by The Post this summer. More than 600 other donors are considered members of the finance council, required to give or raise $5,000 each.

Smith invited the co-chairs to gather for a dinner on Nov. 20, the night before the broader meeting.
