Here in Texas, we get to hear about our constitution every legislative sesion and election cycle, as it is FUBAR. Itg seems we had a constitution as a republic, then as a state, then Texas seceeded, got readmitted, and was made to draft a new one. Instead of being reasonably vague and allowing for interpretation and dynamic government, the numbskulls who drafted this puppy specified EVERYTHING. Now, the constitution must be ammended for pay raises, procedural changes, land sales, and all variety of nonsense. There are, literally, HUNDREDS of ammendments to the Texas state constitution. Occasionally, a state legislator will propose drafting a new one, but it doesn’t seem to be a popular idea.
Seconding what Danimal said about state constitutions, yes, they often give broader interpretations of U.S. Constitutional protections. Many good examples of this exist in criminal procedure, particularly in the area of search and seizure.
Also, on the OP, we don’t hear much about state constitutions because one of the largest roles they play is in the U.S. Supreme Court decisions most people never read, i.e. cert grants/denials (the decision of the Court to hear or not hear a dispute). If there’s an independent and adequate state ground (usually found in the state’s constitution) for a STATE supreme court’s decision, the U.S. Supreme Court won’t hear the case.
