Shocked, Jimmy Carter seems like such lovable guy.

WASHINGTON — Former presidents Bill Clinton and George H.W. Bush have united — in their hatred of Jimmy Carter.

The former commanders-in-chief share a disdain for their fellow ex-president because he conducted foreign policy after leaving office without any authority from the White House, according to a new book.

In “The Presidents Club: Inside the World’s Most Exclusive Fraternity,” former staffers even use the word “treason” to describe Carter’s actions.

“Carter gives the club a great gift, something for all the others to complain about,” the book by Time magazine’s Nancy Gibbs and Michael Duffy says.
