Joan Rivers: Obama and Romney 'both idiots'

"How dare you spend two years campaigning. This country's in trouble," said Rivers in an interview that aired on CNN's "Starting Point" Wednesday.

The host of "Fashion Police" lamented the drawn-out presidential campaign season in the United States and advocated for a system more like the United Kingdom's.

"Six weeks to find out what everyone thinks before they vote for them for parliament. That makes sense. Two years?" River said.

The televesion personality, never shy to speak her mind, showed no leniency for either the president or the presumptive GOP nominee.

"First of all, Mr. President, get into the White House and do your Godd--n duty," she said. "And Mitt Romney, two years, you all hate each other and now they're all going to come together and say 'but we really love him.' I find it disgusting."

Rivers got particularly heated when discussing the amount of money spent on campaigning, calling it "outrageous."

"Obama went to a dinner party for 'Democrats.' Forty thousand dollars a plate. You're not Democrats, you're not Democrats, you're very strong Republicans."

"I find the whole thing disgusting, both sides, disgusting," she added.

Rivers has been on a media tour promoting her new book, I Hate Everyone … Starting with Me.
