Hillary Clinton left the State Department nearly two months ago, but she still needs a staff to keep up with the considerable business of being Hillary Clinton. A half-dozen people now work for the former secretary of state and Democratic presidential candidate in a tiny corporate space on Connecticut Avenue in Washington, in what is called her “transition office.”

Transition to what, Mrs. Clinton and her aides have not yet said. But the question hovers over her every move and has frozen in place the very early — but for some potential candidates, very important — presidential maneuvering on the Democratic side.

Mrs. Clinton’s post-government life is so new that she is barely off her State Department health care plan. The Iowa caucuses are at least 33 months away. But that has not dissuaded a network of former campaign staff members and volunteers from starting a political action committee, “Ready for Hillary,” dedicated to what they hope will be her 2016 run.

Nor has it stopped major polling outfits like the one at Quinnipiac University from seeing how she would do in a presidential contest against two Republican contenders from Florida, former Gov. Jeb Bush and Senator Marco Rubio. In a Quinnipiac poll conducted two weeks ago, Mrs. Clinton thrashed both by 11 percentage points in their home state.
