From an e-mail press release:

FAIRFAX, Va. — USA Next Chairman Charlie Jarvis blasted AARP’s just released poll on Social Security as “misleading and biased,” and vowed to get the truth out to AARP members as well as Congress and the general public.
“It looks as if AARP has a serious TRUTH-IN-POLLING problem. AARP’s misleading and biased survey does a grave injustice to AARP members, Congress and the general public,” Jarvis said. “We are committed to getting the truth about this poll to AARP’s members – as well as everyone else – so people can make informed decisions about the best way to reform Social Security.”
USA Next sent a memo to all Members of Congress featuring an analysis of the poll by nationally renowned pollster John McLaughlin. Among McLaughlin’s findings about the poll:
*The survey includes no respondents under age 30, even though voters age 18 to 29 made up 17% of the 2004 electorate.
*Those age 60+ constitute 34% of the sample, yet they were 24% of the 2004 electorate.
*20.7% of adults receive Social Security benefits. Yet 33% of AARP’s respondents report receiving benefits. This biases results against plans to strengthen Social Security since all surveys show resistance to change among Social Security recipients.
*AARP’s sample gives Democrats a six-point advantage over Republicans (37% to 31%). However, the parties made up equal percentages of the 2004 electorate (37% to 37%).
