History-making governor races of a different kind are being won in New Mexico and Oklahoma, where two women faced off for the governor's seat in both states. It's the first time either state has elected a woman to its top office.
New Mexico switched to red and elected Republican Susana Martinez over Democrat Lt. Gov. Diane Denish. Martinez, who is also the first female Hispanic governor in U.S. history, had held a 10-point lead in the polls for the last week of campaigning.
In Oklahoma, ABC News is projecting that Republican candidate Rep. Mary Fallin will defeat Democratic Lt. Gov. Jari Askins, based on exit polls.
Having a female opponent didn't stop Fallin from taking a few jabs at her challenger over women's issues towards the end of the campaign.
"I think my experience is one of the things that sets me apart as a candidate for governor," Fallin said at a debate in October. "First of all, being a mother, having children, raising a family."
Askins, a former judge who has never been married or had children, later defended herself on "Good Morning America," saying neither marriage nor parenting experience should be a prerequisite for being governor.
Based on exit polls, four other blue states have made the switch to red in the governor's seat: Kansas, Michigan, Wyoming and Tennessee.

In Texas, incumbent Republican Gov. Rick Perry will extend his already decade-long tenure -- the longest in the state's history -- as ABC News projected him to be the winner over Democrat Bill White. Throughout his faltering campaign, White's donors dumped tons of cash into the challenger's war chest but to no avail.
