"You can't tell me the system is better now than it was before Medicare," he said.
Coburn agreed that some people received poor care - or no care - before Medicare was enacted in the 1960s, but said communities worked together to make sure most people received needed medical attention.
He also conceded that doctors and hospitals often went unpaid for their efforts, or accepted baked goods or chickens in partial payment.
Coburn then rejected one townhall attendee's suggestion that President Obama wanted to destroy America but suggested that he wanted to create a culture of dependency because dependency worked out so well for him.
Responding to a man in Langley who asked if Obama "wants to destroy America," Coburn said the president is "very bright" and loves his country but has a political philosophy that is "goofy and wrong."
Obama's "intent is not to destroy, his intent is to create dependency because it worked so well for him," he said.
"As an African-American male," Coburn said, Obama received "tremendous advantage from a lot of these programs."
