The new party is a Chicago based organization and its stated objective absolutely is for the US to adopt European style Democratic Socialism. With initiatives such as Obamacare, excessive EPA regulations driving up gas prices, income redistribution, corporate bailouts etc that is exactly what President Obama is doing. So the revelation that he was a member of the New Party is not all that surprising.
The mainstream press largely agrees with this agenda so they don't see anything unusual to report on. Occasionally the President will make comments that directly state his objective to turn us into Europe as in this quote from a speech in Strasbourg France in 2009.
"In my own country, what I think is very important is that we finally get a health care system that is reliable and cost-effective. That's something that -- (applause) -- you know, that's a social safety net that exists in almost all of Europe that doesn't exist in the United States."
Most of the time however, he hides his true intentions since he knows that the majority of the people will not go along with it.
If I wanted to live in a European style culture, I would just move there. I don’t because I have visited Europe many times and it is a dying society that does not represent how I want my family and myself to live.
