With a high-profile book tour this week, Hillary Clinton is looking to define herself as a foreign policy pragmatist who is willing to chart a different course from that of President Barack Obama.
The reception Clinton gets is likely to help her decide whether to launch a bid to be elected the first woman U.S. president. Polls show she is the overwhelming favorite for the Democratic presidential nomination should she run.
Clinton says she will make up her mind about a presidential run after the November congressional elections, though many Democrats think she will run. Those close to her say the book tour will help her decide.
"I think essentially this is to gauge what the reaction is to the book and gauge what the reaction is as she tours the country," said a Clinton associate.

Her four years at the State Department were not, however, without controversy, and Clinton is using the tour to defend her record and explain her reasoning behind key decisions.
A chapter is devoted to the Sept. 11, 2012, attack by militants on a U.S. facility in Benghazi, Libya, in which the U.S. ambassador to Libya was killed. Republicans have accused then-Secretary Clinton of not doing more to ensure the safety of Americans there.
In an ABC interview airing on Monday night, Clinton said she was "ultimately responsible for my people's safety." But pressed on whether there was more she could have done, Clinton said there were limits.
"I'm not equipped to sit and look at blueprints, to determine where the blast walls need to be or where the reinforcements need to be," she said. "That's why we hire people who have that expertise."
Republicans are vowing to keep
