According to the Department of Health and Human Services, only 0.5% of the population would have been denied heath care coverage due to pre existing conditions prior to Obamacare. Yet the Obama administration over emphasized this factor as an important piece of the Affordable Care Act. The "pre existing denial" was mentioned in speech after speech, but no one ever cited the HHS estimates.
I don't think this topic is anything but a baiter topic to bring out the already stupid, uniformed, fired up miscreants that comb the internet to smear their idiot campaign against topics they have no knowledge or care to. Health Insurance in the US is an abomination and paying for the uninsured and the fat, unhealthy lifestyles of the minimally insured is the cost crippler of the system. Some 'debate'.
