It appeared that the Supreme Court was on the right track in interpreting the Commerce Clause until this [censored] case came up:

In U.S. v. Morrison the Supreme Court struck down a provision of the Violence Against Women Act that would allow them to bring civil suites in federal court.
In U.S. v. Lopez the court struck down the Gun Free School Zones Act because it was beyond Congress' Commerce Clause authority.

...and then came the Raich case.

(It is also interesting to note that Congress passed the Civil Rights Act under the authority of the Commerce Clause.)
