Quizplus · Accepted Answer

Poole and Rosenthal's NOMINATE scores show that if legislators align themselves along a consistent and reliable ideological continuum, roll call outcomes can be predicted consistently. This suggests that ideology is a strong predictor of voting behavior, rather than media or other factors. Additionally, their scores have shown that both Democrats and Republicans have become more polarized over time, rather than just one party.
