In Reynolds v Sims, 377 U.S. 533, at page 535, the U.S. Supreme Court said, “The right to vote freely for the candidate of one’s choice is the essence of a democratic society, and any restrictions on that right strike at the heart of representative government.”
In Wesberry v Sanders, 376 U.S. 1, at page 17, the Court said, “No right is more precious in a free country than that of having a voice in the election of those who makes the laws under which, as good citizens, we must live. Other rights, even the most basic, are illusory if the right to vote is undermined.”
Justice Douglas wrote in Williams v Rhodes, 393 U.S. 23, at page 39, “A state has precious little leeway in making it difficult or impossible for citizens to vote for whomever they please.”
The persons who wrote the 14th amendment, section three, never imagined that the section could dictate whom voters could or could not vote for. The restriction in Section 3 concerns who can hold an office, not whether anyone can be prevented from voting for any candidate he or she wishes.
