Gas in the Philadelphia area has been quite touchy recently. I think it has been around 3.94 is most areas, but I've seen regular as high as 4.20 in areas of population and such.
The speculation really needs to be limited or possibly stopped all together. It really makes no sense to allow people to speculate on products that are required for a stable economy. Gold and silver I understand, but not oil...

Now, as far as domestic drilling... Domestic drilling will do nothing to help the oil prices in the US. All oil is traded on the global market and most of what we get out of the ground ends up going to other countries.
Now the health care costs... thats not 100% due to Obamacare either. Health care costs are going up because more and more people are losing their jobs. Well, those people that have lost their jobs still need medical care. They are either forced to go on Medicaid and such or simply not have health insurance. The people that don't have health insurance at all have been flooding the hospitals with non-emergency issues. Since they have no money, they don't pay the bills and the hospitals need to recoup that money somehow. This doesn't account for the entirety of the increase, but it has a rather huge impact. My old job that I worked at from 2007 to 2011 had to switch their heath care provider in '07, '08 and '09 due to the rising costs. Obama wasn't even in office when they switched in '07 and the price jump was freaking 30% from '06. Obamacare is far from the only factor considering it wasn't even in effect when my old job was constantly swapping health care providers.
