Changes

In his Senate campaign, Clarke faced opposition from two Democratic tickets: (1) the  Truman-Barkley national slate, placed on the ballot through a special session of the state legislature, and (2) the official state party line taken that year by [[Strom Thurmond]], then a [[segregation]]ist governor of [[South Carolina]] and later an eight-term member of the U.S. Senate. Thurmond switched allegiance in 1964 from the Democrats to the Republicans to support [[Barry Goldwater]] over President [[Lyndon B. Johnson]]. Clarke considered the two opposing Long slates "illegal". Though no such situation of this kind had been undertaken previously in Louisiana,  candidates in New York could then and still may combine their general election votes from rival party slates. Clarke sued to prevent the Truman-Thurmond slates from both offering Russell Long as their senatorial nominees, but the appeals court declined to hear the case.<ref name=interview/><ref>Billy Hathorn, ''The Republican Party in Louisiana, 1920-1980'',  ([[Natchitoches, Louisiana|Natchitoches]]: [[Northwestern State University]], 1980), p. 49</ref>​

For a brief time, Clarke appeared poised for a breakthrough. Leander Perez of Plaquemines Parish in [[suburb]]an New Orleans was then the chairman of the powerful Louisiana Democratic State Central Committee. He opposed  a generous tidelands oil lease settlement offered by the Truman administration and held out for a greater advantage to Louisiana, which never materialized. In a dispute with then Governor [[Earl Long|Earl Kemp Long]], Perez threatened to deprive Russell Long, Earl Long's nephew, from securing the official state Democratic nomination. Such a move would have denied Long a place on the Democratic Thurmond column, the ticket with the traditional rooster emblem, which was automatically the choice of tens of thousands of Louisiana voters at the time. Perez toyed with passing the official Democratic mantle to Clem Clarke. Only a deal between Perez and Governor Long kept Russell Long on the Thurmond slate,<ref>{{cite web|url=http://louisianavoice.com/2010/08/11/earls-big-blunder-no-thanks-to-leander-perez/|title=Earl’s big blunder (no thanks to Leander Perez)|publisher=Louisiana Voice|author=Tom Aswell|date=August 11, 2010|accessdate=February 10, 2015}}</ref> which carried the Louisiana [[electoral vote]]. Russell Long subsequently served for thirty-eight years in the Senate until he stepped down in 1987 and was succeeded by fellow Democrat [[John Breaux]].​

Clarke tried to convince Thurmond voters to cast split tickets, then unheard of in Louisiana general elections, and to support him, not Long, for the Senate. Clarke claimed that there were a "lot of shenanigans at the polls, and the split vote that I got where they were voting for Thurmond and for me, I doubt very seriously if they were counted and given to me. ... Of course, a lot of these votes were given to me on account of the anti-Long feeling in Louisiana (yet Earl Long had won the governor's election earlier that same year). I am proud to say that I did carry my home city of Shreveport against Russsell Long."<ref name=interview/> Clark also won in East Baton Rouge, Iberia, and [[Lafayette]] parishes. By plurality, Iberia was the only parish to support Dewey.<ref>Louisiana Secretary of State, Presidential election returns by parish, November 2, 1948</ref>​
