I think so, but I am not a lawyer. Doing more research seems to suggest that depending on how the law is written, it could still fall under state laws. Basically, they can't make it illegal to get an abortion out of state, because interstate laws like that would be federal. However, there are workarounds. For example, if they were to pass a law defining a fetus at X weeks development as "human life", then they can literally claim going to another state to get an abortion falls under the purview of committing murder.Wouldn't such a thing fall under the purview of the federal government?
Long story short, it's a bit complicated, and I don't fully understand it, but while there are currently no laws to actually prevent interstate travel for the purposes of an abortion yet, the possibility is there.
