In 2004, he urged people to "vote or die" with a flashy campaign. This time around, Diddy let cameras into the voting booth with him.
"People died for us to have this right," the rap mogul says in this clip, which shows him casting his vote in New York City Tuesday. "So to exercise this right today is to give back to Martin Luther King and Rosa Parks and everyone who fought for us."
"As a representative of the youth vote, you know, I think this year we're going to shock the world and break all the numbers, all the records ever."
Although he doesn't specifically call out Barack Obama in the video, Diddy – who turns 39 on this election day – has made his support for the Democratic candidate clear in the past.
Referring to the black community, Diddy says, "We're not going to vote for anyone just because they're black. We're going to vote for the best candidate. He has to be extra qualified for us to vote for him. "
