U.S. House
On a multi-state Place, each row sums votes cast in the separate U.S. House races held inside the Place that year. It is a geographic vote total, not one contest or a seat tally.
Some U.S. House rows cover a contest held in only part of this Place — the votes are real, but the total is not place-wide because the rest of the Place had no such race that year.
