I don’t believe that the pollsters have an agenda. At least not all of them. The ones who have an agenda are the ones who hire them to conduct the polls. You know - the ones who cut the checks and then say something like, “I want you to do a national poll on the outcome of this election. Assume a massive Dem turnout even greater than that of 2008...”
If they are putting their names on information they know to be false they are whores.
