From the Jewish Daily Forward in September 2012:

Why Are So Many French Jews Voting for Front National?

Numbers Soaring for Far-Right Party, Survey Finds By JTA Published September 14, 2014. The number of Jews who voted for the far-right National Front party soared in the most recent presidential election from the previous two votes, surveys showed. In the surveys of French Jews, some 13.5 percent of 1,095 respondents who self-identified as Jews said they voted for National Front President Marine Le Pen in the 2012 presidential elections. Asked about the two previous presidential elections, from 2002 and 2007, respectively only 6.1 percent and 4.3 percent of Jewish voters polled said they chose the National Front candidate — Le Pen’s father and predecessor as party leader, Jean-Marie Le Pen, who has a history of convictions for “inciting racial hatred” and Holocaust denial. … Overall, National Front candidates received 19.2 percent of the vote in the first round in 2002 and 10.6 percent and 19 percent in the first rounds in the following two elections. … Former French President Nicolas Sarkozy of UMP received more than 45 percent of the votes of Jews polled in the first rounds of both the 2007 and the 2012 elections — far above his share of the votes in the general voter population.

Sarkozy’s favorite grandparent was his lone Jewish one.

So the Sarkozy + Le Pen share of the Jewish vote was close to 60% in the first round of the last French presidential election.

Were there any other right of center parties in the first round of the 2012 election? I was disappointed to see that the Hunting, Fishing, Nature, Tradition Party didn’t field a candidate in 2012 in contrast to 2007.

The Socialist Party, which is believed to have been a favorite among Jews in the 1970s and 1990s, fell far behind Sarkozy in the poll of Jews, nabbing 19.7 percent, 28.8 percent and 22.5 percent of the Jewish vote in the first rounds of the presidential elections of 2002, 2007 and 2012, respectively.
