If I believe my vote in an election was diluted by an ineligible candidate being allowed on the ballot , what would be my cause of action ? Would it be an infringement on my freedom of expression ( 1st amendment ) or of my 14th amendment rights or infringement of my civil rights ? Also , laws / duties of the BU were omitted , therefore allowing this ineligible candidate on the ballot . . . would that be another cause of action ( fraud , dereliction of duty , malfeasance , neglect ) ?
You do not have a personal cause of action. Whatever "damages" you suffered were not localized or specific to you-- they were (allegedly) borne by all voters of the State of Maryland.
