In what circumstances will the US Supreme Court strike down a ban on write-in voting?

22 See also Wright v. Richter (D.Del.1969) 301 F.Supp. 1345, in which the court abstained from ruling on the validity of a prohibition on write-in voting in order to "avoid[ ] a premature and perhaps unnecessary federal constitutional question." (Id., at p. 1349.) The court preferred to let Delaware's state courts address the issue, noting that most states have held such a ban to be unconstitutional under their state constitutions. (Id., at pp. 1347-1348.)
