> So the sentence should be the unprecedented electoral success of an extreme right wing party in France?

Its not even clear that the particular results are tied to the attack. While the connection seems attractive to draw, it leaves out consideration of the fact that, while the result was unprecedented for this particular kind of election, FN won a unprecedent success in a different set of French elections last year -- being the leading party in France in the European Parliament elections (following a series of successes in France municipal elections earlier in the year) and securing more than a third of France's seats; it seems a lot more like the FN is just having a surge of popularity that predates the attacks by a least a year, and that that was the source of the results earlier this month, rather than the attacks led to the results this month.
