Exactly how you can exercise your constitutional rights depends on where you live.
That's because an increasing number of states have established their own laws on abortion and guns.
Alabama Republicans this year have passed new restrictions on abortion clinics and loosened limits on where citizens can carry guns. In liberal states such as New York and California, meanwhile, Democratic lawmakers have shored up access to abortion and tightened rules on guns.
On both issues, critics of the measures say they threaten protected constitutional rights.
Georgetown law professor Randy Barnett says that's just the nature of law and politics.
Barnett notes that U.S. Supreme Court decisions usually allow for lawmakers to pass legislation regulating constitutional rights. So opponents who don't like the bottom lines of those decisions take advantage.
