Although many candidates sought the Republican nomination, only two, Governor Alfred Landon and Senator William Borah, were considered to be serious candidates.[citation needed]
The following candidates ran only in their home state's primary or caucus for the purpose of controlling its delegate slate at the convention and did not appear to be considered national candidates by the media.
The following persons were listed in two or more major national polls or were the subject of media speculation surrounding their potential candidacy, but declined to actively seek the nomination.
With Knox's candidacy withdrawing in order to become Landon's selection for vice president, and Day, Green, and Warren releasing their delegates, Landon's victory was assured.
