(In order of appearance, beginning around 5 p.m. MDT)
John Boehner: Current U.S. Speaker of the House Boehner is the second oldest of 12 brothers and sisters and has lived in Ohio for his entire life. He was elected to Congress in 1990. Recently reelected for an 11th term, Boehner took the House gavel from former U.S. Speaker Nancy Pelosi when Democrats lost their House majority after the 2010 election.
Reince Priebus: Priebus is from Kenosha, Wis. He was elected Chairman of the Republican National Committee on Jan. 14, 2011. He served on his first political campaign when he was 16 years old, and later worked with the Republican Party of Wisconsin as 1st Congressional District chairman, State Party Treasurer, First Vice Chair and State Party Chairman. In 2009 he served as General Counsel to the Republican National Committee.
Mia Love: Mayor of Saratoga Springs and a current congressional candidate running against Jim Matheson, Love was asked to address the Republican convention by the Romney campaign. Love will become the first black Republican woman in Congress if she wins in November, and she has been gaining attention outside of Utah. Ann Romney, Paul Ryan, Boehner and John McCain have endorsed her, and Former U.S. Secretary of State Condoleezza Rice will be visiting Utah on Sept. 7 to voice her support as well.
Rick Santorum: A one-time rival in the Republican race for the White House, Santorum represented Pennsylvania in the House and the Senate before he entered the 2012 Republican presidential primary. He won 11 states, but his exit from the race in April virtually assured Romney the party's nomination. In May, Santorum endorsed Mitt Romney, saying that although the two candidates disagreed over many things, they agreed that President Obama must be defeated. Santorum released the delegates he won during the GOP primary, freeing them up to support Romney during the convention.
Kelly Ayotte: A U.S. senator from New Hampshire, Ayotte was rumored to be on Romney's short-list of vice presidential candidates. Kelly was the first woman to serve as attorney general in New Hampshire. She was first named attorney general by a Republican, and then was reappointed twice by Democratic Gov. John Lynch. She is currently the top Republican on the Armed Services Subcommittee on Readiness and Management Support, and serves on the Armed Services, Budget, Commerce and Small Business Committees in the Senate.
Gov. Scott Walker: Walker, 45th governor of Wisconsin, recently told Politico that Romney's pick of Ryan as running mate will carry a Wisconsin victory for the Republican ticket in November. Walker's career in public service includes eight years as the Milwaukee County Executive and five terms in the Wisconsin State Assembly, where he earned a reputation as a supporter of cracking down on crime and curtailing welfare programs, as well as a staunch pro-life advocate on abortion issues. Before entering politics, Walker worked for IBM and the American Red Cross.
Artur Davis: A former congressman who officially seconded Barack Obama's nomination in 2008, Davis is a former co-chairman of Obama's presidential campaign. Davis left the Democratic Party in May, saying that the party had changed and that the current Democratic Party "is not Bill Clinton's Democratic Party (and he knows that even if he can't say it)." Davis also said that, "the symbolism of Barack Obama winning has not given us the substance of a united country."
Nikki Haley: South Carolina Gov. Haley was elected in 2010, becoming the 116th governor of South Carolina. Haley was born in Bamberg, S.C., and is the daughter of Indian immigrants. Haley is South Carolina's first female governor and the second Indian-American governor in the United States (the first being Bobby Jindal, R-La.). Haley was first elected to represent the 87th District in Lexington County in 2004 and served until she won the governorship. She endorsed Romney in December 2011.
Ann Romney: Ann Lois Davies married Mitt Romney on March 21, 1969, and together they raised five songs — Tagg, Matt, Josh, Ben and Craig. In 1998 she was diagnosed with multiple sclerosis, an autoimmune disease that affects the central nervous system. She rediscovered horseback riding while living in Park City prior to the 2002 Olympics, and that helped her deal with her MS. In 2008 Romney was diagnosed with ductal carcinoma in situ, a noninvasive type of breast cancer, and underwent a lumpectomy. When her husband was considering another run for President of the United States, Romney asked, "Can you fix the economy?" When he said yes, she said, "I'm on your team."

He was elected as governor of the state in 2010 and began taking on pension reform for New Jersey's public service unions. Christie is known for his combative tone as governor, which his staff highlights through YouTube videos.
