Several things that aren't right in this article :
"Old Continent" -> "old continent"
"Barack Obama’s election in 2008 was greeted with popular enthusiasm in Europe and seen by European politicians"
Utterly WRONG : in the United Kingdom from Day 1 people were worried because the Conservatives had endorsed the Republican candidate McCain and people feared that there would very bad relations between the Conservatives (who everyone know were going to win the elections) and the Democrats who have very distant social/economic policies.
"it is a general lack of interest in Europe that characterises the US electoral debate."
Why should the Americans care for Europe ? They have enough topics such as birth control, guns, welfare system to discuss before they are going to discuss Europe. We do live in a high interconnected world but even Canada is a non-issue during American election campaigns.
"The eurozone crisis is indeed more important to the day-to-day life of the US than are the Russian elections or Chinese hegemony. But few candidates seem to remember that."
Have you polled the American people, or are you all-knowing ? I highly doubt that, especially with Putin's re-election and the rise of China has America's economic competitor, and the flood of Chinese goods on American markets.
"Opposing old, weak and inspiration-less socialist Europe"
Your article is way too simplistic, there isn't one but several Europes in the eyes of the Americans. The one that is failing (Southern Europe), the one that will fail (France, Spain) but the Americans still look up to the Germans, to the Scandinavians and the Swiss for instance. To say that they bash "Europe" is wrong in itself. Not all of Europe is old, weak and socialist, your sentence contradicts itself. What they criticize is seen as a degeneration of what Europe gave them (Britain invented liberalism, France gave VAT and so on) and what some made of it.
It's easy to plagiarise articles such as http://www.csmonitor.com/World/Global-News/2012/0111/Is-Mitt-Romney-s-Eu... but you should maybe take into account while you copy/paste them that their point of view is not always right or lacks contrasts.
