“If there is to be responsible party government, the party label must be something more than a mere device for securing office. Unless those who are elected under the same party designation are willing to assume sufficient responsibility and exhibit sufficient loyalty and coherence, so that they can cooperate with each other in the support of the broad general principles, of the party platform, the election is merely a mockery, no decision is made at the polls, and there is no representation of the popular will.”
