If Roe is overturned, abortion policy might not be left to the states

But this state of affairs could change if Congress decided to act. In my view, the text and original meaning of the Constitution do not give Congress any power to restrict abortion, with the exception of those performed in federal territories, such as the District of Columbia, and perhaps those that involve crossing state lines to access a commercial provider. But current Supreme Court precedent strongly suggests otherwise.

Under cases such as Gonzales v. Raich (2005), the Supreme Court has held that Congress’ power to regulate interstate commerce includes the authority to restrict almost any “economic activity,” so long as it has a “substantial effect” on interstate trade. And “economic activity” is defined very broadly to include anything that involves the “production, distribution, and consumption of commodities.” That definition allowed the Court to use the Commerce Clause to uphold a federal ban on the possession of marijuana that had never crossed state lines or been sold in any market (even an intrastate one). Nearly all abortions involve the “consumption” and “distribution” of commodities, such as medical supplies. In addition, most abortions qualify as “economic” transactions because doctors, nurses, and others are paid to perform them.

One could argue that a federal law banning or severely restricting abortions isn’t “really” aimed at regulating interstate commerce. The true motive would be to restrict abortion regardless of whether it involved interstate transactions or not. But much the same can be said for the marijuana ban upheld in Raich, and other federal laws enforcing the War on Drugs. They go far beyond targeting actual interstate trade in drugs, and instead forbid even in-state distribution and possession of illegal narcotics.
