Republican Gov. Susana Martinez looks for a possible mandate from voters and a boost to her national political standing as New Mexicans decide whether she'll serve a second term as the nation's only female Hispanic governor.

If Martinez wins as expected Tuesday over Democratic challenger Gary King, it could solidify her reputation as a rising GOP star with the ability to appeal to independents, moderate Democrats and Hispanics.

Martinez maintains she's uninterested in a national office and has pledged to serve a full four-year if re-elected. But that's unlikely to stop speculation over her future as a possible GOP vice presidential contender as the focus shifts to the 2016 presidential campaign.

Martinez rocketed to national prominence four years ago in becoming the nation's first Latina governor.
