A view about how parties should work, held by some political scientists:1. Parties must present distinct, comprehensive programs for governing the nation. 2. Each party's candidates must be committed to its program and have the internal cohesion and discipline to carry out its program. 3. The majority party must implement its programs, and the minority party must state what it would do if it were in power. 4. The majority party must accept responsibility for the performance of the government.
