http://overtimepolitics.com/overnight-emails-and-a-few-questions-answered/Firstly one would expect a polling company to reveal facts about itself like the name of people involved and it's location. This guy comes out and admits it is a one man operation and it is actually a "side project". He also promises to stop attacking candidates on Twitter and ask more than one question in polls, so I guess those weren't already kind of givens for a polling company. And yet, even still he finds time to attack Clinton and the DNC for being 'unfair' to Sanders.
I'm sorry, this is not a real pollster and I don't see why these 'numbers' should even be posted here anymore. There has to be some barest sense of legitimacy, this is just some Bernie fan trying to pull an old school Rasmussen, but at least Rasmussen actually did some polling (biased and flawed but there were polls being done). There is no evidence this is anything more than just some guy in his spare time making up numbers.
