James Clark McReynolds,
Newberry v. United States — Opinion of the Court
“ It is matter of common knowledge that the great mass of the American electorate is grouped into political parties, to one or the other of which voters adhere with tenacity, due to their divergent views on questions of public policy, their interest, their environment, and various other influences, sentimental and historical. So strong with the great majority of voters are party associations, so potent the party slogan, so effective the party organization, that the likelihood of a candidate succeeding in an election without a party nomination is practically negligible. ”
