No, I don't think something significant will happen. Please keep in mind that Harvey is not a fool. He knows very well that these polls can be manipulated. Everybody knows that TMZ polls allow multiple votes from the same IP address. All they have to do is pull the file from the database and it will show that hundreds of votes were made from the same IP address.
Opinion polls are designed to represent the opinions of a population. The results of this particular poll make it perfectly clear that the hoaxers had a huge hand in it.
