WASHINGTON (CNN) - Experts call it the "forgotten issue," or even the "ignored issue" - Social Security.
Sens. John McCain and Barack Obama have spent ample time addressing the budget crisis, but haven't zeroed in on the growing concerns over Social Security.
Maya MacGuineas, president of the Committee for a Responsible Federal Budget, says it's not an accident that McCain and Obama have skirted the issue.
"I think both Obama and McCain ended up thinking talking about fixing [Social Security] was a political loser," MacGuineas said. "So they were just happy letting the issue disappear."
The Obama campaign disagrees with that assertion.
"We have talked about it quite extensively both at our events and in our paid media, as well as in terms of policy," Obama campaign spokesman Hari Sevugan said.
"There is a real difference in the approach that Sen. Obama would take in ensuring the long-term health of Social Security. The primary difference being that Sen. Obama wouldn't risk Social Security savings to the whims of the stock market like John McCain would," said Sevugan.
The McCain campaign's Web site says the Arizona senator is committed to revamping the system:
"John McCain will fight to save the future of Social Security and believes that we may meet our obligations to the retirees of today and the future without raising taxes. John McCain will reach across the aisle, but if the Democrats do not act, he will. No problem is in more need of honesty than the looming financial challenges of entitlement programs."
