Nick Jonas had bigger ambitions than just topping the charts -- because he's thinking President.
In an interview with Parade, Nick talks about meeting President Barack Obama -- and says his family actually calls him "Mr. Prez," adding “It was a joke at first,” he says. “Then, I thought, 'Man, it actuallywould be cool to run for President one day."
FYI -- You gotta at least 35 to be Prez ... Nick's only halfway there.
