The pre existing conditions argument is stupid to begin with. First of all, there may be a lot of people with "pre existing conditions" but that's not the same as being uninsurable. Only people who have chronic AND severe problems would be considered uninsurable by a company.

And second of all, why shouldn't people who drain more out of the system have to pay more into it? I understand it sucks to be born with a genetic illness and have to pay more insurance, but you're also costing everyone in the market more money. Its the sad reality we have to deal with and until we find to train doctors as easily as we train fry cooks, healthcare will never be entirely "affordable" to everyone.
