Through the executive branch because no one is going to stop him...
Gun control. First it will be universal registration via back ground checks. And to make it extremely difficult to own or purchase firearms it will be wrapped up in Obamacare as a public health menace.
Abortion. No restrictions whatsoever. No state laws governing abortion.
Internet. No anonymous handles. Any and all bloggers or commentators will be required to enter a publicly available address and identity. All political speech and debate will be eliminated via campaign election laws.
Private property. All private property will be subject to EPA regulation. No exceptions.
Climate change. All automobiles will be subject to new federal emission standards. Vehicles out of compliance must be replaced within 6 months of failure. Used automobiles will not be permitted. Repairs are not an option. Exemptions will be made to illegal aliens and those without financial means to purchase a new car will be given an Obamacar.
Taxes. There won’t be new taxes. Only extra fees and mandatory payments with names like “Children First Supplement” or “Atmospheric Justice and Fairness Assessment.”
States’ Rights. All but eliminated with federal regulation dictating all state laws and regulations must meet or excede minimum federal standards.
Immigration. Open the flood gates. “Refugees” will continue to be moved to rural areas and red state holdouts. All will be given the right to vote.
I heard on a morning radio show a couple of guys joking around about baraq and what he will do in the future. One of them said that baraq would pardon all of his favorite people from the US prisons at the end of his term. For a short second that seemed crazy, but given that he has no restrictions it seems very real.
