John McCain taps Alaska Gov. Sarah Palin as VP

Less than 24 hours after Barack Obama became the first black person to accept a leading party's presidential nomination, Republican rival John McCain stunned observers--and arguably political insiders--by tapping Alaska Gov. Sarah Palin as his running mate.

McCain made the announcement in Dayton, Ohio, moments ago, and Palin introduced herself and her family to those inside the auditorium and the country. The McCain clearly wanted to tap into the potentially lucrative women's vote this November--and perhaps wanted to court Hillary Clinton supporters who may remain disenchanted with Obama's nomination. The question remains, however, who is Palin and what is in her closet. She has denied any wrongdoing, but state lawmakers launched an investigation into the matter.

Palin's conservative credentials have also come under close scrutiny. Human Rights Campaign President Joe Solmonese was quick to criticize her support of a state constitutional amendment to ban marriage for same-sex couples that passed in 1998 and her opposition to an Alaska Supreme Court decision that mandated the state to extend benefits to the partners of its gay and lesbian employees--even though her veto essentially provided these benefits.

"America may not know much about Sarah Palin, but based on what our community has seen of her, we know enough," Solmonese said.

NARAL Pro-Choice America President Nancy Keenan further criticized Palin for her stance against abortion.

"John McCain's choice of Sarah Palin as his running mate proves just how rigid and extreme his administration would be when it comes to a woman's right to choose," she said.

McCain's decision to choose Palin is certainly historic, but a number of serious questions, including whether she has enough experience for the job, remain. She has a lot to prove in the next two months.
