Obama pushed for single payer universal healthcare but the moderate Democrats in the Senate wouldn't go for it so he settled for what we have now. The ultimate tax hike is Obamacare which now forces young people to buy insurance at a much higher rate then before. I explained here years ago that the Obamacare plan should have been a catastrophic coverage/hospitalization only plan. Instead we got an expensive turd of a bill that costs a ton of money and hurts alot more people than it helps.
As of this moment the President is on a tour promoting banning certain types of weapons. He won't be able to pass anything but he is certainly trying. Here in NY State in January Governor Cuomo effectively banned 95% of the currently legal weapons. Obama would do the same given the opportunity.
Regarding wellfare rolls Obama by executive fiat rolled back some of the requirements put in place by Clinton in the wildly successful welfare reform act of 1996 essentially undoing what was a very successful program. And if food stamp rolls are not being grown on purpose I'd ask you why I keep hearing commercials for the program encouraging people to sign up.
