"We called a State Of Emergency on October 3rd at 6:00 AM and our culture stood up and recognized the importance of registering millions of voters. From 1st time voters who have just come of age to vote, to those who are participating for the 1st time in the voting process. Your commitment to Change will continue to ring across our America, because we all are in the Right State Of Mind.

"Where it stands today, we are on the verge of making history, the kind of history that will be a part of our culture's legacy. The kind of history that bridges the gap between race, religion and culture, the kind of history that will ignite a light that shines bright from generation to generation, screaming that our voice does matter and our vote does count.

"The kind of history that will enable the next generation of leaders to encourage vision, not division, to encourage hope, not hopelessness, to encourage the power of the people, not the power politics of the few.

"With only 7 days left before we vote for change, let's hold ourselves accountable and responsible. No more excuses, no more mistakes and no more time to waste. If you have the opportunity to vote early in your state then vote today. If you are voting on November 4th, make preparations today.

"Bring your family and friends and plan for the party at the poles. Make November 4th the day we celebrate change - The day we celebrate freedom of choice. The day we celebrate power of all people. Lets all come together on November 4th, because it's a family reunion. It's our time and we are all in the Right State Of Mind.

"We have 7 days to Vote for Change. 7 days to Vote to Make History. We can not slow down. We can not let up. We must push through to history until the final vote is cast and the last ballot is counted. We can, we must, and we will Make It Happen. Vote Obama/Biden on November 4th.

Diddy
