CREATE TABLE table_name_61 (total_seats INT, share_of_votes VARCHAR)

When the share of votes equals 21.8%, what's the sum of the total amount of seats?
SELECT SUM(total_seats) FROM table_name_61 WHERE share_of_votes = "21.8%"
SELECT SUM("total_seats") FROM "table_name_61" WHERE "21.8%" = "share_of_votes"
