Answer:
a federal presidential constitutional republic.
Step-by-step explanation:
The United Mexican States is a federal presidential constitutional republic made up of 31 autonomous states —and one federal entity, called Mexico City, its most populous and important region, which, for all practical purposes, shares in the same autonomy as the rest of the 31 states but it is not a state itself— that respond to or abide by a federal, presidential and constitutional rule. Each state is furthermore divided into different municipalities.
