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 table_50754 ( "Poll source" text, "Date(s) administered" text, "Sample size" real, "Margin of error" text, "Joe Sestak (D)" text, "Pat Toomey (R)" text, "Other" text, "Undecided" text )

### Question ###
WHAT DATE DID JOE SESTAK HAVE 46% WITH 3.0% MARGIN OF ERROR?

### Accurate SQL ###

SELECT "Date(s) administered" FROM table_50754 WHERE "Joe Sestak (D)" = '46%' AND "Margin of error" = '± 3.0%'
