You know her because: She is a U.S. senator from New Hampshire and was among the names circulated for Romney's running mate.
Why Republicans love her: As a 44-year-old woman, she presents a difference face of the Republican Party and could help appeal to women voters.
Why Democrats don't like her: Ayotte is against abortion rights and cosponsored the Respect for Rights of Conscience Act, which restores the ability of healthcare providers and companies to conscientiously object to providing birth control services. [See a collection of political cartoons on the Republican Party.]
You know him because: He's the governor of Ohio, was a U.S. representative, and had a talk show on Fox News.
He doesn't want you to remember: After getting pulled over in 2008 for violating public safety, Kaisch later called the officer who stopped him an "idiot." Clips of his comment and traffic stop both ended up on YouTube.
Why Republicans love him: Kasich reduced the Ohio unemployment rate from 9 percent to 7.9 percent in his first year in office, and also eliminated the state's $8 billion budget deficit.
Why Democrats don't like him: In March of 2011, he signed a bill abolishing the collective bargaining rights of public workers. Opponents collected enough signatures to get a referendum placed on the ballot in the November election, where Ohio voters resoundingly defeated it and restored workers' bargaining rights.
You know her because: She's the first woman governor of Oklahoma.
She doesn't want you to remember: One week after her divorce in 1998, when Fallin was lieutenant governor, one of her bodyguards resigned after admitting to "unprofessional conduct." Her husband alleged that Fallin had an affair with the man.
Why Republicans love her: Fallin believes the government should serve the people, "not the other way around."
Why Democrats don't like her: After first saying she would accept it, Fallin rejected a $54.6 million grant to develop an Oklahoma state health insurance exchange, the creation of which is required by the Affordable Care Act. Fallin does not support the federal healthcare law and hopes to see it repealed with the election of Romney. Bob McDonnell
You know him because: McDonnell is the governor of Virginia and chairman of the Republican Governors Association.
He doesn't want you to remember: In his 1989 Masters thesis, "The Republican Party's Vision for the Family: The Compelling Issue of The Decade," McDonnell said working women and feminists were "detrimental" to a family.
Republicans love him because: The governor opposes the Affordable Care Act and signed a bill seeking to nullify the provision in the law that requires people to purchase health insurance.
Democrats don't like him because: He signed a controversial mandatory ultrasound bill into law in Virginia, which requires a woman to have an ultrasound at least 24 hours before the performance of an abortion. [See a collection of political cartoons on the Tea Party.]
You know her because: She is a candidate for lieutenant governor of Delaware.
She doesn't want you to remember: Valenzuela, who started a business with her husband in order to pay for their son's autism treatment, will highlight the convention's theme of "We Built This." Yet Valenzuela's business has received more than $2 million in federal loans and encourages others starting businesses to seek out government help.
Why Republicans like her: As the owner of her own business, she speaks on the importance of small business in the economy. Ted Cruz
You know him because: A former Texas solicitor general, he's a Tea Party favorite who upset establishment favorite Lt. Gov. David Dewhurst in the 2012 Senate primary in Texas.
Why Republicans love him: As a Cuban-American, if elected, Cruz could help the GOP appeal to the country's growing number of Latinos.
Democrats don't like him because: Cruz thinks Islamic law threatens to take hold in the United States and believes "Sharia law is an enormous problem."
