President Obama's peeps say Mitt Romney is gonna be sorry for blowing off a bunch of kids who participated in the Nickelodeon show, "Kids Pick the President."

The premise of the show -- kids submit questions to each candidate and based on the answers they make their pick for leader of the free world.

Obama answered the kids' questions, but Romney said he didn't have the time.

Deputy National Press Secretary Adam Fetcher tells TMZ, "It's no surprise Romney decided to play hookey. Kids demand details, and I'm sure they want some answers on why Romney could increase their class sizes, eliminate their teacher's jobs, raise taxes on their families and slash funding for Big Bird."
