There are three requirements for standing: Injury, causation, and redressability.
Injury: The plaintiff must have suffered or imminently will suffer injury - an invasion of a legally protected interest which is concrete and particularized. The injury must be actual or imminent, distinct and palpable, not abstract. This injury could be economic as well as non-economic.
Causation: There must be a causal connection between the injury and the conduct complained of, so that the injury is fairly traceable to the challenged action of the defendant and not the result of the independent action of some third party who is not before the court.
Redressability: It must be likely, as opposed to merely speculative, that a favorable court decision will redress the injury.
The voter or campaign contributer in an election is by definition subject to “injury”, like participation in any contest. But if the rules of the contest are violated, an injury to the process has occured.
In politics -- you only hurt the ones you love.

Sounds like any citizen has all three:
Injury: A free and fair election is a right, and anything that interferes with it, such as a sham candidate, causes injury to every American with suffrage.
Causation: Obama’s running
Redressability: A court order to remove him from ballots and/or prevent his swearing-in as President.
