CNN — There were two Ryans onstage Saturday at the largest retirement community in the country: The Republican vice presidential candidate and his mom.
House Budget Chairman Paul Ryan of Wisconsin got a helping hand from his mother Betty, a retiree who lives part-time in the Sunshine State, as he promised to protect Medicare and attacked President Barack Obama over the popular federal health insurance program for seniors.
"Medicare was there for our family, for my grandma when we needed it. Medicare is here for my mom when she needs it now and we have to keep that guarantee. My mom has been on Medicare for 10 years, but I won't tell you exactly how many years over 10 years she's been on it," Ryan told a large and very supportive crowd consisting mainly of retirees and those nearing retirement age.
"She planned her retirement based around this promise that the government made her because she paid her payroll taxes into this program that she had this promise with. That's a promise we have to keep."
Since presumptive Republican nominee Mitt Romney announced the seven-term congressman as his running mate one week ago, Medicare has become a much-battled-about issue on the campaign trail.
The Obama campaign and fellow Democrats instantly attacked Ryan over the budget plan that he introduced in the House, terming it a "radical plan" that would benefit the rich at the detriment to the middle-class, and they highlighted his proposals to alter Medicare, which they said would "end Medicare as we know it."
The Romney campaign has fired back, accusing the president of cutting the entitlement program to pay for his signature health care reform law.
Ryan continued that attack Saturday.
"Here's what the president won't tell you about his Medicare plan, about Obamacare: The president raids $716 billion dollars from the Medicare program to pay for the Obamacare program," he said.
But he also added a new line as he touted the GOP ticket's proposals, saying "we think the best way to save Medicare is to empower 50 million seniors, not 15 unelected bureaucrats to make their decisions in how they get their health care. Mitt Romney and I will protect and strengthen Medicare so that the promises that were made, that people organized their retirements around like my mom, will be promises that are kept."
The president and his re-election campaign are pushing back against the GOP attacks. A new television commercial running this weekend in key battleground states rebuts the Romney-Ryan charges with the narrator in the spot saying "the non-partisan AARP says Obamacare 'cracks down on Medicare fraud, waste, and abuse,' and strengthens guaranteed benefits."
And the commercial criticizes the Ryan proposals on Medicare, with the announcer adding that "AARP says it would undermine Medicare and could lead to higher costs for seniors. And experts say Ryan's voucher plan could raise future retirees' costs more than $6,000."
The Romney campaign is getting the $716 billion figure from a July 24 Congressional Budget Office report which measured the impact of repealing the health care overhaul law, which Romney has promised to do.
The report says that under the repeal measure, "Spending for Medicare would increase by an estimated $716 billion over that 2013-2022 period." Those spending increases would be a result of more spending on hospital and medical insurance, offset by a decrease in prescription drug coverage.
The report also notes that the projected $716 billion increase in Medicare spending if the the health care law is repealed does not signal a $716 billion decrease if the measure stays in place - which is Romney's argument.
Although the purpose of the event was to tout the campaign's position on Medicare, Ryan also pitched the Republican ticket's economic message using his mother's background as a source of inspiration for him.
"You know, growing up, my dad worked and my mom stayed at home. I've got three older siblings -- a sister and two brothers. And my mom stayed at home those years. When my dad died, my mom went back to school, she went back to college, got a new skill or a new trade and she started a small business. My mom had three or four employees at that small business that she started," he said.
Getting choked up, Ryan turned to his mom who was sitting in a chair behind the stage and said, "Mom, I am proud of you for going out and getting another degree. I am proud of you for the small business that you created and mom, you did build that!"
Ryan was referring to a comment Obama made at a campaign event in Virginia in mid-July when he was trying to make an argument for public investments like infrastructure and education that support the private sector.
"If you are successful, somebody along the line gave you some help. There was a great teacher somewhere in your life. Somebody helped to create this unbelievable American system that we have that allowed you to thrive. Somebody invested in roads and bridges. If you've got a business, you didn't build that. Somebody else made that happen," Obama said at the time.
The Romney campaign and Republicans have been attacking the president over the "you didn't build it" line ever since, using it on the trail, on t-shirts and bumper stickers, and in a television commercial. Democrats say the line was taken out of context.
The Villages, which is just more than an hour northwest of Orlando, has become a must stop for presidential candidates, both in the primaries and in the general election. Romney held an event here when he was battling for the GOP nomination. And Sarah Palin drew a large crowd at the Villages four years ago when the then-Alaska governor was Sen. John McCain's running mate on the Republican ticket.
Obama narrowly won Florida four years ago. The most recent polling this time around has Obama holding a single-digit advantage in the battle for the state's 29 electoral votes.
