Here is a weekend factoid for you: among all living politicians in the United States who have ever held elected office, Hillary Clinton the most popular.
That's right. Ever since she became Secretary of State, her favorables have soared into the mid-60's, putting her well clear of any other statewide officeholder in the country. The only national figures who are viewed as favorably as Clinton are Michelle Obama, Colin Powell, and David Patraeus. However, they have never run for office, which invariably lowers your favorables.
Hillary Clinton will turn 69 in in the final week of the 2016 campaign, which makes her slightly younger than Ronald Reagan when he first was elected in 1980. Also, as Secretary of State, a major presidential candidate, a U.S. Senator, and First Lady, she is also probably more credentialed than any other potential Presidential candidate, too. There is even talk she may become the next Secretary of Defense, further adding to her credentials.
Some have said that, in choosing Joe Biden as Vice-President, Barack Obama did not pick a successor to lead the Democratic Party. However, that needs rethinking. Because Barack obama made her Secretary of State, Hillary Clinton remains remarkably well-positioned to run for President in 2016, even more so than she was in 2008.
