mysql select statement date comparisons

[esbsolu]

$sinceDate = date('m-d-Y');
$query="SELECT * FROM `pollinfo` WHERE pollClientID=2 and isLive=1 and DATE_FORMAT(startDate,'%m-%d-%Y')<=$sinceDate ORDER BY startDate DESC";

Can anybody tell me if this is in correct form?

Thanks!

you don't need the PHP variable:

SELECT * FROM pollinfo WHERE pollClientID = 2 and isLive = 1 and startDate <= CURDATE ORDER BY startDate DESC
