Most candidates no-shows so far at AARP event

All but one of the presidential contenders could pick up some helpful life hints -- as well as address an important voting bloc. But so far only two of them have committed to an AARP event Friday in Boston.

Democrat Hillary Clinton and Republican Mike Huckabee plan to speak to the "Life@50+" forum, which is expected to draw more than 25,000 AARP members, relatives, and friends to the Boston Convention and Exhibition Center. The event is billed as part class reunion; part home, travel, health, and high-tech expo; and part summer concert weekend.

The AARP said today that all the major presidential candidates were invited, and others could accept this week. Of the hopefuls, only Democrat Barack Obama, at 46, is under 50 years old.
