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_name_72 ( sample_size INTEGER, date VARCHAR, margin_of_error VARCHAR )

### Question ###
What was the sample size for the poll from Nov 9-11, 2007 with a margin of error less than 4.3?

### Accurate SQL ###

SELECT MAX(sample_size) FROM table_name_72 WHERE date = "nov 9-11, 2007" AND margin_of_error < 4.3
