Rogers Clark Ballard Morton (September 19, 1914 - April 19, 1979) was an American politician who served as the U.S. Secretary of the Interior and Secretary of Commerce during the administrations of Presidents Richard M. Nixon and Gerald R. Ford, Jr., respectively. He also served as a member of the U.S. House of Representatives from Maryland. Though he was born in Louisville, Kentucky, Morton moved to a farm on the Eastern Shore of Maryland in the early 1950s. In 1962, he was elected to the House of Representatives, in which capacity he established an environmental record.

In 1969, leading up to the 1970 elections, Morton was considered one of the strongest potential candidates to challenge incumbent Democratic senator Joseph Tydings. Morton had sought the Republican nomination for Maryland's other U.S. Senate seat in the 1968 elections, but bowed out in favor of Charles Mathias, Jr. to prevent a primary battle. Speculation that Morton would seek election to Tydings' seat increased after an editorial in the Baltimore Sun encouraged him to challenge Tydings. Sources within the administration of Vice President Spiro Agnew, who was formerly governor of Maryland, were also commenting that Morton would make a strong candidate and would likely run. When Morton stated he would be making an important announcement with President Nixon in December 1969, it seemed all but certain at the time that it would be to declare his candidacy. However, Republicans around the country were concerned that Morton, who had just been appointed chairman of the RNC in January 1969, would resign during the election season to better handle the battle with Tydings. President Nixon shared their concerns, and encouraged Morton to remain as chairman. On December 16, 1969, with Nixon by his side, Morton announced that his priorities were with the national committee, and that he would not seek Tydings' seat. Morton also threw his full support for the nomination behind John Glenn Beall Jr., a freshman member of the Maryland Senate. Morton's decision not to challenge Tydings initially worried Maryland Republicans, who saw Morton as one of their best candidates. National Republican strategists had also begun to write off Tydings' seat as unwinnable for the 1970 election because of Tydings's wealth and popularity in the dense urban areas of Montgomery County and Baltimore. However, despite initial misgivings by state republicans, Beall defeated Tydings on November 3, 1970, by a margin of more than 30,000 votes.
