Sen. Kelly Ayotte (R-N.H.) will march with Mitt Romney in a Fourth of July parade in her home state, her office and the Romney campaign confirmed Tuesday.

The public appearance makes Ayotte the only vice presidential possibility to campaign with Romney during his Independence Day vacation. Romney and his extended family are gathered at their nearby home on the banks of Lake Winnipesaukee for the week.

Romney, prior to securing the GOP nomination or launching the vetting process, named Ayotte as one of the possibilities for his list of running mates.

She has said it “would be quite enjoyable” to face Vice President Biden in a debate. Ayotte told the Boston Herald in May, “It’s certainly an honor to be mentioned for consideration as vice president, but serving New Hampshire in the Senate is the greatest honor I could ask for.”

Ayotte serves as co-chairwoman of Romney's national advisory committee. She is often named as a possible sleeper pick for the job as Romney’s No. 2.
