Now, I don't live in the US, but all this talk about Obama being an "evil" socialist seems a bit farfetched. As Orcus kind of said, the people who make claims like that probably just associate socialism with bad things because its what they are lead to believe.
There's nothing inherantly wrong with socialism, just as theres nothing inherantly wrong with capitalism. They are just two, albeit slightly different means to an end. The economy is all about satisfying needs and wants, socialism does it with a touch more collectivism that capitalism, which is more about the individual.
I live in Australia, which is probably somewhere between a capitalist democracy and a socialist democracy. We have basic universal healthcare, unemployment benefits, tax breaks for low income earners, a government-funded student loan system and all kinds of other social safety net policies to ensure that everyone has a chance if they want it.
From what I can tell, the US has very little in the way of social safety nets, besides maybe basic healthcare for poorer people. Everything is provided by the market; you apply for unemployment insurance, you get health insurance from your employer, you get student loans from a bank. Again, there is nothing inherantly wrong with this, its just one of many ways of solving resource allocation problems.
At the other end of the spectrum is scandanavian countries, who tax 50 cents in the dollar and provide free healthcare, public transport, educatio etc. Once again, nothing wrong with this, its their ideology and their way of satisfying societies needs and wants.
It seems the current US government is leaning towards introducing more social safety nets in the form of a medicare-type program that guarentees healthcare (again, I'm not 100% on this). That doesn't make Obama a socialist (again, I don't associate being "socialist" as evil because its not), it means he is trying to correct a perceived market failure.
If anything, the article is endemic of the toxic political culture in the US at the moment.
