If they are putting their names on information they know to be false they are whores.
But... they don’t know that it’s false. They are simply giving their customers what they want. If their customer wants to know how the campaign is going based on the same turnout as 2008, why should Joe’s Polling Service say, “Sorry. I won’t take your money. I don’t think the turnout’s going to be anywhere near that. Take your check and shove it.” They sell a service. If someone wants to pay them perfectly good money to run a poll based on ridiculous assumptions, why should they say no?
