Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE election ( Delegate VARCHAR, District VARCHAR )
TABLE: CREATE TABLE county ( County_id VARCHAR, Population INTEGER )

### Question ###
How many distinct delegates are from counties with population larger than 50000?

### Accurate SQL ###

SELECT COUNT(DISTINCT T2.Delegate) FROM county AS T1 JOIN election AS T2 ON T1.County_id = T2.District WHERE T1.Population > 50000
