I'd say yes and no.
In terms of things the President has an affect on no. Me and my family are paying less in taxes. My daughters health insurance garnered her a rebate due to "Obama care". My wife and I didn't, because of different rules for HMOs.
In those things the government has little or no control over, yes. Gas, of course, is out of control. Although, as I type this, a teaser for the evening news mentions that it's coming down, even if it's only a little. Food has gone up, but in most cases is a result of flooding diminishing crops, or drought producing small crops. And with these factors, feeding and watering cattle and such has increased costs.
The bottom line is that the programs that Obama and the Dems have gotten through have had some success. They stopped the free fall that the economy was in, and have brought unemployment down. The Republicans have had good success in stopping the Left in most cases, putting party before Country, which I personally find so UN-Patriotic. It boggles the mind that the Right seriously thinks that a return to the ideology and practices that got us in this mess in the first place is the answer to getting us out of it.
And;
So your telling me that the past four years have been Romney's fault? um, ok...
He certainly helped. Just think about Bain Capital "leading the charge" in moving manufacturing jobs out of the country, and try to believe he didn't have anything to do with this mess.
