All-or-nothing votes.

We vote for parties, not issues, so we’re forced to take the whole package, even the parts we disagree with.

A ballot picks one candidate, usually with a party name. In the House, recorded votes usually follow that party.

One vote, one candidate

The candidate with the most votes wins the seat. A party may endorse only one candidate in a district, and that party’s name can appear on the ballot.
