A just-released survey from the seniors lobby AARP finds that older voters want candidates to better explain their plans for Social Security and Medicare. The poll also showed that Americans over age 50 are anxious about their retirement security and dissatisfied with politicians.

“The message from voters 50+ is clear,” AARP Executive Vice President Nancy LeaMond said in a statement. “In a razor-tight election, candidates have a major opportunity to reach key voters by speaking about their plans on Social Security and Medicare — and they are making a huge gamble if they ignore them.”

AARP’s “Anxiety Index” found that 75 percent of those surveyed worry about rising consumer prices, while 73 percent report that they are worried about not having enough money during retirement.

While the demographic is also worried about jobs, those concerns rate lower than fears over the future of entitlement programs. And nonretired baby boomer voters are pessimistic about retirement: 72 percent of respondents said they believe they will have to delay leaving the workforce.

Nearly half, 49 percent, of the older voting bloc disapproved of President Barack Obama’s job performance, and 81 percent said they disapprove of Congress.

They are split equally, however, between voting for Obama or presumptive GOP nominee Mitt Romney, with 45 percent for each candidate and the other 10 percent saying they were not sure who they’d vote for.

Ninety-one percent of the older voters said the economic and retirement issues are too big for one party to solve alone and that solutions require bipartisanship.

AARP said it commissioned Hart Research Associates and the GS Strategy Group to conduct the survey by telephone July 10-16. The groups polled almost 2,000 registered voters.
