The issue before the Supreme Court has nothing to do with medical nor pre-existing. Just more scare / false tactics by the Left Democrats. The issue before the Supreme Court is SEVERABILITY. Meaning; If 1 part of an overall legislation is deemed unconstitutional does that then render the legislation as a whole null and void. Using the ACA, if the individual mandate forcing people to buy something or being penalized with a tax was deemed unconstitutional (it was) does stripping that out render the whole ACA null and void. There is no Judge deciding pre-existing or anything else other then the issue of severability which applies to numerous laws written by Congress. For those who do their homework you should know that John Roberts thinks not and more recently Judge Kavanaugh wrote a legal article where he supports (legally) severability. Meaning he does not think if one part of a law is stripped then the entire law gets scrapped. If Roberts and Kavanaugh vote that way then ACA minus the individual mandate will stand as the law as flawed as it is.
