the race and then dropping out. Nixon was the front runner throughout the contest because of his superior organization, and he easily defeated the rest of the field. Nixon's first challenger was Michigan Governor George W. Romney. A Gallup poll in mid-1967 showed Nixon with 39%, followed by Romney with 25%. After a fact-finding trip to Vietnam, Romney told Detroit talk show host Lou Gordon that he had been "brainwashed" by the military and the diplomatic corps into supporting the Vietnam War; the remark led to weeks of ridicule in the national news media. Turning against American involvement in Vietnam, Romney planned to run as the anti-war Republican version of Eugene McCarthy. But, following his "brainwashing" comment, Romney's support faded steadily; with polls showing him far behind Nixon, he withdrew from the race on February 28, 1968. Senator Charles Percy was considered another potential threat to Nixon, and had planned on waging an active campaign after securing a role as Illinois's favorite son. Later, however, Percy declined to have his name listed on the ballot for the Illinois presidential primary. He no longer sought the presidential nomination. Nixon won a resounding victory in the important New Hampshire primary on March 12, with 78% of the vote. Anti-war Republicans wrote in the name of New York governor Nelson Rockefeller, the leader of the Republican Party's liberal wing, who received 11% of the vote and became Nixon's new challenger. Rockefeller had not originally intended to run, having discounted a campaign for the nomination in 1965, and planned to make United States Senator Jacob Javits, the favorite son, either in preparation of a presidential campaign or to secure him the second spot on the ticket. As Rockefeller warmed to the idea of entering the race, Javits shifted his effort to seeking a third term in the Senate. Nixon led Rockefeller in the polls throughout the primary campaign, and though Rockefeller defeated Nixon and Governor John Volpe from Massachusetts primary on April 30, he otherwise fared poorly in state primaries and conventions. He had declared too late to get his name placed on state primary ballots. By early spring, California governor Ronald Reagan, the leader of the Republican Party's conservative wing, had become Nixon's chief rival. In the Nebraska primary on May 14, Nixon won with 70% of the vote to 21% for Reagan and 5% for Rockefeller. While this was a wide margin
