Any state certainly has standing, in fact sole control over who accesses their ballot within certain standards. And how.

Another candidate? Questionable.

[mlo]

Another candidate is exactly who has standing.

Not so.

You are not correct. See Davis v. Federal Election Commission SCOTUS decision and cases cited therein.

Note the following passage from that case: "A party facing prospective injury has standing to sue where the threatened injury is real, immediate, and direct. Los Angeles v. Lyons , 461 U. S. 95, 102 (1983); see also Babbitt v. Farm Workers , 442 U. S. 289, 298 (1979) (A plaintiff may challenge the prospective operation of a statute that presents a realistic and impending threat of direct injury). Davis faced such an injury from the opera- tion of §319(a) when he filed suit. Davis had declared his candidacy and his intent to spend more than $350,000 of personal funds in the general election campaign whose onset was rapidly approaching."
