Why do Democrats want no voting rules?

It is not baseless conspiracy theorizing to wonder why Democrats seem so focused on eliminating voter rules and jeopardizing basic voter principles, such as only citizens should vote in elections or election deadlines should mean something.

A Chinese student who is legally in the country but is not an American citizen cast a ballot in Michigan after falsely identifying himself as a citizen and registering to vote using his student ID. He is facing around 15 years in prison for perjury. His ballot was illegally cast, and he is going to be incarcerated for it, and yet Michigan apparently has no standards or safeguards in place to prevent this from happening because the state already counted his ballot and confirmed his vote will count.
