Trustee, Delegate, and Politico Models
These are three models of how a representative decides what to vote for: a trustee uses their own judgment, a delegate follows district opinion, and a politico switches between the two depending on the issue.
Every representative faces the same question on every vote: do what the district wants, or do what you think is right? The trustee model answers 'what's right.' A trustee studies an issue, weighs evidence, and votes on their own best judgment, even if most constituents disagree. The delegate model answers 'what they want.' A delegate treats themselves as a messenger for district opinion, voting the way polls or letters or town-hall feedback say to vote, whatever their personal view. The politico model splits the difference: on technical or low-visibility issues, act like a trustee; on high-salience issues the district cares about and watches closely, act like a delegate. Most real legislators behave like politicos, sliding along that scale issue by issue.
Term length pushes that slide. A House member stands for reelection every two years, so their vote record gets judged again almost immediately, which rewards tracking current district opinion closely, a delegate-style pull. A senator's six-year term buys more distance from the next election, giving more room to vote as a trustee on an unpopular call and let memories fade before voters weigh in again.
This connects to accountability and to how outside groups now track votes. When interest groups publish scorecards and ratings on every roll call, a 'trustee' vote stops being quietly forgotten. It becomes a permanent, public data point an opponent can use in the next campaign, which squeezes even trustee-minded members toward voting with their district more often.
