The indictment charges that on or about January 1, 1950, and continuously thereafter until December 14, 1950, when the indictment was filed, the appellants and divers other persons feloniously conspired to injure citizens of the United States in the free exercise and enjoyment of their right to vote for legally qualified persons for the offices of United States Senator and United States Representative in Congress from Alabama, in a primary election to be held on May 2, 1950, in the State of Alabama, as an integral part of the procedure provided by the statutes of Alabama for the election of United States Senators and Congressmen; that it was a part of said conspiracy to obstruct, prevent, and hinder, legally qualified citizens from voting in that election, and to cause disqualified persons to impersonate qualified citizens and to vote in their place; that it was a part of said conspiracy to cast false, forged, and fictitious votes, at said primary election, with the intent that said illegal votes should be counted and thus should dilute, diminish, and destroy, the value and effect of votes legally cast, with the further purpose of causing the election officers to make a false return and certification of the results of said election.
