California Congressman Duncan Hunter is the first candidate to pay for television advertising time on New Hampshire airwaves for the 2008 presidential election.
The ad, which began airing on WMUR-TV in Manchester today, shows Hunter in front of a fence on the border with Mexico.
CNN is reporting the ad also airing in Iowa.
Hunter announced in South Carolina Wednesday he is running for president. He will visit New Hampshire on Monday.
Last month, DraftObama.com paid for ads on cheaper cable networks encouraging Illinois Senator Barack Obama to run for president.
