Can the pre-existing condition clause survive without the individual mandate? Dr. Sanjay Gupta explains

Tomorrow the Supreme Court will rule on President Obama’s health care law. The individual mandate, which requires all Americans to purchase insurance or face a penalty, is the most contentious part of the law.

CNN’s chief medical correspondent Dr. Sanjay Gupta discusses the law with Soledad O’Brien on Starting Point this morning.

Pragmatically, Dr. Gupta says that due to monetary concerns, it's difficult to see how the law will work if the individual mandate is thrown out but the pre-existing condition clause remains. He explains that the profit from the mandate is intended to offset the costs of providing coverage for people who are chronically ill.

Up to 50 million people in the United States currently don’t have health insurance.
