Do conservatives realize there's absolutely no chance of repealing the healthcare bill?

Healthcare is a "quintessentially economic" activity which gives Congress the right to regulate it under the Commerce Clause. For the last 80 years the USSC has upheld virtually every interpretation of the Commerce Clause, even in cases where the economic activity in question was much less obvious than healthcare. In order for the USSC to strike down the healthcare bill they'd have to overturn 80 years of precedent. In other words - they'd have to be "activist" judges.
