One main difference between the united states constitution and state constitutions is that state

b. can't be amended.
c. don't have bills of rights.
d. don't provide for a legislature.

Generally speaking, one main difference between the United States Constitution and state constitutions is that state constitutions "are much longer", since they have to deal with the intricacies of the states themselves.
