the geographical map of the population, a deputy would need only 5,000 votes to be elected in some districts (such as in Saint-Barthélemy) while it would need 180,000 votes in others (such as the Seine-Saint-Denis). The Constitutional Council noted that this contradicted article 6 of the 1789 Declaration of the Rights of Man and of the Citizen as well as articles 3 and 24 of the Constitution. Campaign Opinion polls and seat projections gave President Nicolas Sarkozy's UMP-led coalition a wide lead, sometimes nearing three-quarters of all 577 seats. The UMP polled marginally above 40%, around a 10-point increase over its score of 33% in the first round of the 2002 elections. Prime Minister François Fillon, also a candidate in Sarthe, led the UMP campaign. On the far-right, following Jean-Marie Le Pen's relatively low score in the presidential election, the National Front tried to regain lost ground in the legislative election, but opinion polls gave the FN only 4 or 5 per cent of votes, one of its lowest scores in a general election. Socialist Party The Socialist Party's defeated 2007 presidential candidate, Ségolène Royal, also campaigned on behalf of her party, even though she did not run for re-election as a deputy in Deux-Sèvres. The Socialists sought to prevent the UMP from winning too wide a majority that would give Sarkozy "full powers". Union for French Democracy Between the two rounds of the presidential election, the UDF leader François Bayrou had announced the creation of a new political party, the Democratic Movement (MoDem), and refused to continue the alliance between centrists and the UMP. This strategy was dangerous for the centrist MPs, one month before the legislative election. The ballot system for the election of the deputies favoured the coalitions to the detriment of the isolated parties. In this, contrary to Bayrou, the most part of the UDF deputies and senators called to vote for Nicolas Sarkozy in the second round of the presidential election, then joined the "Presidential Majority" and founded the New Centre. Incumbent president of the UDF group in the National Assembly, Hervé Morin, led this new political formation and was nominated Defense Minister. For the first time, François Bayrou was challenged by a right-wing candidate in his constituency. Interest in one local election race surrounded Gérard Vignoble of the UDF, who had represented Roubaix since 1988. Vignoble announced that he would not stand again since
