Theoretically, the way a public option would work would be similar to the Medicare system already offered to older adults. President Obama and his supporters feel the public option would be a way for uninsured Americans to obtain insurance since it would be available to all Americans at an affordable cost and would not exclude individuals for pre-existing conditions.
Opponents feel a government run insurance program available to all Americans, like the proposed public option, would be unfair competition to insurance companies since the government run pubic option would attract more customers and put private insurance companies out of business therefore causing a huge cost burden on taxpayers.
