Older Americans are often caregivers. And they vote.

Sandy Haas wants to pick the candidate she hopes will be the best president for her children and grandchildren.

But when she thinks about casting a ballot this fall, what's also on her mind is how much smaller she is than her husband Roy.

She barely tops 5 feet and weighs 100 pounds less than her 6-foot-2-inch-tall former-police officer husband, who has been severely disabled for more than a year. When she tries to help him transfer from the bed to his wheelchair, or into the shower, she's always worried he might fall.

Her osteoporosis means she's very likely to break a bone if he topples onto her. "Then we're really in a pickle," she said.
