During a press conference yesterday, President Obama voiced support for government-administered health insurance for all who need it (aka the "public option"), as a key component of healthcare reform. Though Obama stopped short of threatening to veto a bill that didn't contain such an option, he said that a public option is needed to enforce market discipline. If the system is going to reform, the health insurance companies can't just keep selling the same bad coverage with bigger public subsidies for their monopolies. Essentially, Obama isn't about to force taxpayers to buy overpriced insurance from private companies.
