On July 19, the Nebraska Democratic Party urged the Secretary of State to rule that he can’t be an independent candidate in Nebraska, because he is a minor party nominee in certain other states. See this story.
The Democratic Party letter ignores the fundamental point that the true candidates in a presidential election in November are the candidates for presidential elector. Technically, there is no “presidential election” in the United States. Instead, in November, there are 51 separate elections for slates of presidential elector candidates. The elections are separate. It is of no importance that Kennedy has elector candidates in some states that are independents, while in other states they are members of a one-state party.
Every minor party or independent presidential candidate of any consequence in U.S. history has used a mix of methods to get on the ballot. This is true for Theodore Roosevelt in 1912, Robert La Follette in 1924, Congressman Thomas Lemke in 1936, Henry Wallace in 1948, Strom Thurmond in 1948, George Wallace in 1968, Congressman John Schmitz in 1972, John Anderson in 1980, Ross Perot in both 1992 and 1996, and every Libertarian and Green presidential nominee 1976 through the present.
