opinion: Per Curiam.
  The motions to affirm are granted and. the judgments are affirmed.
  Mr. Justice White and Mr. Justice Goldberg join the affirmance in No. 623 since it is their understanding that it in no way interferes with the power of the District Court, in the light of circumstances as they may develop, to vacate or .otherwise modify its order requiring an election in the fall of 1965.
