Title: Richard Nixon

Title: Operation Sandwedge
Content:  In 1968, Richard Nixon, the Republican Party nominee, won the presidential election, defeating Democrat Hubert Humphrey, the incumbent Vice President. Nixon's margin of victory in the popular vote was seven-tenths of a percent. Nixon had previously contested the 1960 election, narrowly losing to Democrat John F. Kennedy by a margin of less than 118,000 votes, which amounted to less than two-tenths of a percent of the total.

Title: Richard Nixon 1968 presidential campaign
Content:  The 1968 presidential campaign of Richard Nixon, the 36th Vice President of the United States, began when Nixon, the Republican nominee of 1960, formally announced his candidacy, following a year's preparation and five years' political reorganization after defeats in the 1960 presidential election and the 1962 California gubernatorial election. En route to the Republican Party's presidential nomination, Nixon faced challenges from Governor George Romney of Michigan, Governor Nelson Rockefeller of New York, Governor Ronald Reagan of California, and Senator Charles Percy of Illinois.

At this time, reports suggested that Nixon would formally announce his bid in February.
