I met one of Hillary's cult followers working on an Illinois campaign. He mentioned the talking point about her visiting more countries than any other Secretary of State. Well, sure, since most of them didn't have air travel. So what?
The most embarrassing foreign policy decision of Obama's administration was Hillary appearing publicly with the new President of Honduras to legitimize the illegal military coup in that country. I assume Obama approved that and it's shamefully disappointing. It was a reminder of Bill Clinton's hostility toward socialist democracies in Latin America.
The biggest scandal of Obama's administration was the inappropriately close relationship Hillary's former staffers lobbying for the Keystone XL Pipeline had with State Department officials.
Obama was smart to bring her inside the tent but I can't think of any reason to be sad she's gone.
