Primary race Nixon was the front-runner for the Republican nomination and to a great extent the story of the Republican primary campaign and nomination is the story of one Nixon opponent after another entering the race and then dropping out.

Nixon's first challenger was Michigan Governor George W. Romney. Romney's grandfather, a member of the Church of Jesus Christ of Latter-day Saints, had emigrated to Mexico in 1886 with his three wives and their children, after the U.S. federal government outlawed polygamy. However Romney's parents (monogamous under new church doctrine) retained their U.S. citizenship and returned to the United States with him and his siblings in 1912. Questions were occasionally asked about Romney's eligibility to hold the office of President due to his birth in Mexico, given an asserted ambiguity in the United States Constitution over the phrase "natural-born citizen". By February 1967, some newspapers were questioning Romney's eligibility given his Mexican birth.
