Tell me the delegates of the county named Howard.
select t2.delegate from county as t1 join election as t2 on t1.county_id = t2.district where t1.county_name = "Howard"
How about its committees?
select t2.committee from county as t1 join election as t2 on t1.county_id = t2.district where t1.county_name = "Howard"
just show me the counties which have at least two delegates.
select t1.county_name from county as t1 join election as t2 on t1.county_id = t2.district group by t1.county_id having count(*) >= 2
