Party affiliation is the most important and consistent predictor of voting behavior in Congress. Members of Congress tend to vote with their party on most major issues, reflecting the party’s platform and ideology. Party affiliation provides a clear framework for a member’s policy preferences and values, and also shapes the incentives and pressures they face as elected officials. While other factors such as personal beliefs and constituent interests may also influence voting behavior, party affiliation is the strongest and most reliable predictor.
