Issues with Duplicate Votes

I verified it is still breaking on dupes. I wrote a quick script that deletes duplicates, and now it's running. Script is pasted below in case anyone else wants to grab it (this could almost definitely be done with less lines of code, I was just trying to get something together).

include_once 'includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

	HAVING

$result = db_query($q_dupe_people);
