CREATE TABLE county (County_id VARCHAR, Population INT)
CREATE TABLE election (Delegate VARCHAR, District VARCHAR)

Which delegates are from counties with population smaller than 100000?
SELECT T2.Delegate FROM county AS T1 JOIN election AS T2 ON T1.County_id = T2.District WHERE T1.Population < 100000
SELECT "T2"."Delegate" FROM "county" AS "T1" JOIN "election" AS "T2" ON "T1"."County_id" = "T2"."District" WHERE "T1"."Population" < 100000
