The burden of going forward with the evidence has been well summarized: (1) The burden remains upon a party until he has satisfied the judge that his evidence is sufficient to go to the jury. (2) It shifts to or is cast upon the opposite party only when the proponent's evidence is sufficient to entitle him to a ruling that the opponent shall lose if he fails to come forward with evidence. McCormick and Ray, Texas Law of Evidence, s 28. The method pursued by contestant to prove the lack of qualifications was a correct one. McCrary on Elections (4th Ed.), s 469;
McCormick v. Jester, 53 Tex.Civ.App. 306, 115 S.W.2d 278, 283. Bur McCrary, in Section 469, states with reference to such proof: ‘If the district or territory within which the voter must reside is large, or very populous, and the witness has not an intimate and extensive acquaintance with the inhabitants, the evidence will be of little value, and standing alone will avail nothing.’ An examination of the evidence adduced from contestant's witnesses shows that they possessed a tremendous lack of knowledge about the election district, its inhabitants, and the voters in question. The knowledge of the witnesses was discredited on cross-examination.
