Voter ID would have helped IF it was done properly. To get ID in Nevada you need to show your SSN, Birth Cert, passport, or DD214. One document MUST have your SSN on it. So requiring ID to vote and making sure you tie up all the holes where illegals get IDs illegally either fake, by using fake documents, or simply by paying a bribe to a worker at the DMV. If the laws were enforced fully and checked, then polling station workers knew how to spot fake IDs and routine identity check questions then no issue.
