It's round two in the race for the Republican presidential nomination, with voting beginning in New Hampshire. While most polling places in the state didn't open until early Tuesday, the first votes were cast just after midnight in the tiny communities of Dixville Notch and Hart's Location.

In Dixville Notch, former Massachusetts Gov. Mitt Romney and Jon Huntsman, the former Utah governor and ambassador to China, tied for the lead with two votes each. Former House Speaker Newt Gingrich and Rep. Ron Paul of Texas had one vote apiece.
