Potential interstate problems: Article 4 of the Constitution
- "Full faith and credit clause": states must honor legitimacy of others
    - Ex: driver's licenses are validated in other states
- Privileges and immunities
    - You don't become an immigrant by moving states
    - Citizen of Georgia = Citizen of Florida
- Interstate extradition
    - Fleeing a crime between states means you get sent back
- Interstate compacts
    - Subject to congressional approval
    - Because this will increase the power/rights of a state
- Still being decided through state powers, census, districting

Two general stages of federalism since civil war
- Dual federalism (1829-1937)
    - Divided based on commerce
    - Interstate = federal domain
        - Limited at the time, local commerce much more common
    - Intrastate = full state control
- Cooperative federalism, started by New Deal (1937-1968)
    - Federally funded but state-administered
    - National Government has a bigger role because they hold the purse
    - Social Welfare motivated in public opinion
- The 1970s have unclear federalism
    - Public opinion turns against feds: Recession, Vietnam, Nixon
- 1980s--present shifts more power to the states
    - President Reagan reshapes federalism
        - Public opinion against big government
        - Block Grants replace states administering specific programs
            with states administering a lump sum social welfare system.
        - Puts blame onto state governments
        - Lets Reagan build up national defense as much as possible
    - Rehnquist Court - Commerce Clasue
        - Expanded definition of intrastate commerce
    - Reverting to dual federalism
- Future
    - FBI and counterterrorism actually hand power back to the states
    - Devolution: shift power from national to states
        - Clarence Thomas - conservative on SC - favors state power
            - Believes it to protect private activity and indiv. freedom
            Arguments:
            - Geographically easy to petition government
            - States control day-to-day bureacracy
            - Federal programs can be shaped to state pops.
            - States innovate new individual rights (ex social programs)
            - You can migrate to shop around for rights
        - Good or bad? Unclear.
        - But there is a greater burden on state finances
