UPDATE 2-Ryan puts personal spin on U.S. Medicare debate

* Fiscal hawk says he would protect Medicare

* Obama: Romney-Ryan would end Medicare "as we know it"

* Health insurance for elderly key issue in Florida

THE VILLAGES, Florida, Aug 18 (Reuters) - Republican vice

presidential candidate Paul Ryan on Saturday put a personal spin

on the debate over Medicare, bringing his 78-year-old mother on

stage at a speech to seniors in Florida where he vowed to

safeguard the health care program for the elderly.

Criticized by Democrats as the author of a cost-cutting

budget proposal, Ryan has tried to distance himself from his own

plan to curb Medicare benefits since Mitt Romney named him as

his running mate a week ago.

Ryan personalized the issue at The Villages, the world's

biggest retirement community and a bastion of Republican support

in a key swing state.

"When I think of Medicare, it's not just a program, it's not

just a bunch of numbers, it's what my mom relies on, it's what

my grandma had," Ryan, 42, said.

Standing in front of a banner that read "Protect And

Strengthen Medicare," Ryan hugged his mother Betty Douglas, who

lives part-time in Florida. The short-haired, diminutive Douglas

waved to the crowd.

Romney's choice of Ryan as his running mate has put a

spotlight on the Wisconsin congressman's best-known achievement

- a budget plan that would slash Medicare's projected costs by

converting it to a program that provides limited subsidies to

buy coverage.

But on the campaign trail, Ryan has moved away from his plan

to emphasize less contentious proposals by Romney.

Talk of shrinking the health program for the elderly could

lose votes in the Nov. 6 election in the hotly contested state

of Florida, home to the highest concentration of retirees in the

country.

"Their plan would put Medicare on track to be ended as we

know it," President Barack Obama said to a crowd of about 2,300

at a campaign event on Saturday in Windham, New Hampshire.

"You'd think they'd avoid talking about Medicare given the

fact that both of them have proposed to voucherize the Medicare

system. I guess they figure the best defense is to try to go on

offense," Obama said.

MEDICARE CUTS

Polls show Romney and Obama running neck-and-neck in

Florida, where the cliffhanger 2000 presidential election was

decided.

Republicans accuse Obama of cutting $716 billion from

Medicare to pay for the healthcare overhaul law that the

Democratic president signed in 2010.

But Ryan's plan also would cut that money from Medicare,

even as he proposes repealing the broader healthcare law. Romney

says he would keep those funds for Medicare.

Ryan talked on Saturday about his grandmother who had

Alzheimer's disease and moved in with him and his mother when he

was in high school.

"Medicare was there for our family, for my grandma when we

needed it then. And Medicare is there for my mom, when she needs

it now. And we have to keep that guarantee," he said.

"But in order to make sure that we can guarantee that

promise for my mom's generation, for those baby boomers who are

retiring every day, we must reform it for my generation."

Medicare benefits nearly 50 million elderly and disabled

Americans, but its financing will be squeezed by the growing

numbers of retirees.

Concerns about the program's future have become the top

healthcare issue in the 2012 election, surpassing worries about

Obama's controversial healthcare law, a Kaiser Family Foundation

poll found earlier this week.

Joseph Bulla, 62, a Romney supporter at The Villages, said

he liked Ryan's voucher plan for Medicare. "It will give us a

chance to choose what we want instead of being dictated to," he

said.
