I have no way of knowing if this is true or not, but I suspect that it is true.

How campaigns try to sway polling results: “In a close race, the operatives are trying to manipulate the turnout through their paid and earned media. The earned media includes lobbying and trying to skew the public polls. Historically the most egregious case was the 2000 Gore campaign’s lobbying the networks’ exit pollsters for an early, and wrong, call in Florida. This suppressed the Florida Panhandle and Western state turnout.” …

What Obama and his allies are doing now: “The Democrats want to convince [these anti-Obama voters] falsely that Romney will lose to discourage them from voting. So they lobby the pollsters to weight their surveys to emulate the 2008 Democrat-heavy models. They are lobbying them now to affect early voting. IVR [Interactive Voice Response] polls are heavily weighted. You can weight to whatever result you want. Some polls have included sizable segments of voters who say they are ‘not enthusiastic’ to vote or non-voters to dilute Republicans. Major pollsters have samples with Republican affiliation in the 20 to 30 percent range, at such low levels not seen since the 1960s in states like Virginia, Florida, North Carolina and which then place Obama ahead. The intended effect is to suppress Republican turnout through media polling bias. We’ll see a lot more of this.
