DW-NOMINATE

A statistical estimate of where a legislator sits relative to everyone else in the same chamber, computed from who votes with whom — never from anyone’s reading of the bills. Published by Voteview, the method is the standard in political science. The number has no units and no meaning outside its own chamber: it says a member votes more like this group than that one, and nothing about whether they were right. It is a position in a voting coalition, not agreement with a programme. Because it is built from who votes with whom, a member who rarely departs from their party sits at that party’s edge of the scale, and one who departs is drawn toward the middle — the scale cannot see which direction the departure came from. In the 119th House that places Speaker-level leadership among the most liberal Democrats and several of the caucus’s most vocal left dissenters nearer the centre. It is a fact about the measure and not about what those members believe, and this site publishes Voteview’s number rather than adjusting it toward what a reader expects. The method also publishes a second dimension, which separates members within each party rather than between them. Voteview does not state what it captures, and nor does this site: a seat’s page gives the figure and where it places that member among their own caucus, with no word for either end.
