Convention organizers stressed on a conference call that while the roll call vote takes place today, Romney and Ryan won't become the official nominees until Thursday. Delegations will be vote alphabetically by state. Organizers said they anticipate Romney will secure the 1,144 threshold needed for the nomination by the time the roll call hits a state that begins with the letter "N."

At 17, Evan Draim of Virginia is the youngest delegate at the Republican National Convention. He told CNN’s Carol Costello why he thinks some younger voters who picked Obama in 2008 will now cast their ballots for Romney.

"I feel like a lot of the freedom and individuality and decision making once left up to private, individual citizens, has now been transferred to the government. And I think that counters a lot of younger citizens’ views about how they should be treated. Younger citizens should want the same freedom from their government that they want from parents and other authority figures at this age. And so I think as we're going into 2012, a lot of younger voters have become apathetic about the election because the candidate they supported so overwhelmingly the last time has really let them down," he said.

According to excerpts from Virginia Gov. Bob McDonnell's speech Tuesday, he will say: "We need a President who will say to a small businesswoman: congratulations, we applaud your success, you did make that happen, you did build that!"

The color guard today is the Fourth Degree Color Guard of the Knights of Columbus from Connecticut and Florida. Leading the Pledge of Allegiance is Former Montana Gov. Tim M. Babcock and Korean War Marine veteran Tom Hogan. Performing the national anthem is tenor Philip Alongi Jr. of New Jersey, who also performed at the party convention in 2008, according to the RNC.

Iowa Lieutenant Governor Kim Reynolds, secretary of the Republican National Convention, reconvenes the event.

According to excerpts from RNC Chairman Reince Priebus’ speech Tuesday, he will say: “Barack Obama thinks the government is at the center of the economic universe. He thinks that if you started a business, ‘You didn't build that.’

“Well, how would he know? President Obama's never run a company. He hasn't even run a garage sale or seen the inside of a lemonade stand. So it's time for a President with real experience in the real economy.”

“Mitt Romney will be that President.”
