Where the 10th Amendment leaves many issues

STATELEVEL

Powers not given to the federal government often fall to this jurisdiction.

The 10th Amendment to the U.S. Constitution states that powers not given to the federal government belong to the states or the people, leaving many issues to be decided at a local level. "State level" fits because it literally describes where those decisions are made—by individual states rather than the national government. The answer plays on the idea of jurisdiction, with "level" hinting at a tier of government. It’s a straightforward reference to how federalism divides authority.
