What might be an advantage of holding state elections separately from federal elections?

An advantage of holding State elections separately from federal elections is that  voters would focus more on State-level issues and candidates.

Explanation:

An advantage of holding state elections on a date other than federal elections is that voters will only have to pay attention to the affairs of the state and its cities, instead of having to think more comprehensively including all the nation. This would generate a more genuine vote towards the state candidates, which would make these elections more real as it would reflect the total thinking of the citizens regarding state issues.

In addition, it would allow state candidates not to see their election influenced by presidential candidates, who often influence the voting of governors according to the political party to which they belong.
