Four years ago, Obama campaigned with hope and change. He ran against George W. Bush's track record, even though Bush was not running again. Today, Republicans campaign with fear and "against Europe", although Europe won't be on the ballot box in November.
For Obama, Bush was "the other" against which he defined himself. For Republicans that "other" is Europe. (See all the Poli Sci literature on collective identities and nationalism) Newt Gingrich in his South Caroline Victoria Speech according to FOX News:
Those two choices, I believe, will give the American people a chance to decide permanently whether we want to remain the historic America that has provided opportunity for more people of more backgrounds than any country in history, or whether in fact, we prefer to become a brand new secular, European-style bureaucratic socialist system.
What does secularism have to do with any of this? I think Newt Gingrich is just listing all the "bad" things he can think of and does not care for European differences. Italy, Ireland, Poland are part of Europe and not that secular. Italy has big economic troubles, Poland not so much. I would leave religion out of it. The Scandinavians are more secular, have less economic troubles and provide more opportunities (social mobility) for their citizens than the US does.
Thomas Kleine-Brockhoff from the German Marshall Fund Blog sums up the Eurobaloney on the Campaign Trail and reminds us that Americans have "traditionally understood their history, culture, and identity in contrast to Europe's."
