Pat Caddell, who has been a democratic pollster for over thirty years is criticizing Reuters for back rigging polls after Donald Trump accomplished a 17 point reversal against Hillary in the polls.  What Reuters has done is go back and eliminate the ones who said they supported neither candidate and reallocated them in order to get the results they wanted.  They then revised all of their previous poll results.  Caddell said that it was lucky for them that there are no laws governing polls because if an accountant did that, he or she would be in prison.

Caddell is a bona fide democrat.  His credits include from Breitbart News:

Reuters has rejiggered its methods in order to get the results they want, said the man, whose out-of-the-box interpretations of the American electorate were the brain-work behind the  insurgent presidential campaigns of Sen. George McGovern (D.-S.D.)  in 1972, Georgia Gov. James E. “Jimmy” Carter in 1976, President Carter 1980 and Sen. Gary Hart (D.-Colo.) in 1984. In 1992, Caddell worked for former California governor Edmund G. “Jerry” Brown, who challenged Arkansas Gov. William J. “Bill” Clinton. In the 1990s, Caddell became a popular cable news guest and consulted on various television and movie projects. The 1984 campaign was a reunion of sorts, because Hart was McGovern’s campaign manager.

Caddell said:

“What they have done is unprecedented.  They have now gone back and changed their results.”

Caddell gave two examples to show what the refiguring did to the polls:

“On July 25, they originally reported: Trump 40.3 percent and Clinton 37.2 percent, which was a Trump margin of 2.8,” he said. “They have recalculated that now–which I have never heard of–they changed that data, to be: Clinton 40.9 and Trump 38.4, which is a 2.5 margin for Clinton.”

The July 25 Reuters poll now shows a result that reflects a 5.3 percentage point flip from the previously published results, he said.

“Now look at July 26,” he said. “On July 26 they had Trump at 41.5 percent and Hillary at 36.3. That was a 5.2 Trump margin. Then, in the new calculation, they claim that Clinton was 41.1 percent, Trump was 37.5, and the margin was 3.6 for Clinton. Same poll. Two different results. Recalculated, after you’ve announced the other results.”

That also changed the Real Clear averages, which showed a 1.1% lead for Trump and now gives Clinton a .4 advantage.

Caddell concluded by saying:

“This idea of ‘We need a poll to give the result we want’ to fit either our ideological or political needs is beyond dangerous.”

“It is dangerous because it drives the news coverage and it is all by design now, which is why everyone is in such shock at what Reuters did.”
