A share is a party's votes over all the votes the Clerk counts for the House, write-ins included.

Votes are counted on each party's own ballot line. A candidate who stood on the lines of more than one party (in New York, Connecticut and South Carolina) has the votes of the extra lines under Other parties, so the Democratic and Republican totals can be a little lower than counts that add the lines together.

Seats are the Clerk's count at the time of the election: a seat that was vacant then is not counted.

How do the votes compare with the seats?
