In the context of voting in the U.S. House of Representatives, "yea" means "yes" and "nay" means "no". "Pres" stands for "present" and indicates the number of Members who voted present and did not vote yes or no. "NV" stands for "not voting" and indicates the number of Members of the House who did not vote. A "present" vote is a refusal to take sides and does not count towards or against the passage of a bill, but it contributes towards the quorum, which is the minimum number of Members required in attendance for the body to conduct business legally.
