My issue with this poll is that it gets included in the RCP everyday. A poll that has the same sample over and over shouldn't be repeatedly put in the RCP.
I think RCP included it because its being sponsored by a major newspaper (it wasn't included under RAND in 2012), otherwise I agree, its a panel poll not a random sample poll. In 2012 when RAND was running it the result was pretty accurate but its a small sample and they could have just gotten lucky. In 2012 the cross tabs weren't available, this year they are and look pretty screwy.
