Nearly half of the senators must be renewed this Sunday.

Elections that will logically be an extension of the municipal elections: after poor results in June, the group of 23 marchers may emerge weakened. 

DECRYPTION

The French from six constituencies will go to the polls on Sunday for partial legislative elections.

But this day is also marked by another ballot, not direct this one: nearly half of the senators must be renewed.

No upheaval is to be expected, the right must remain in the majority.

How many senators will be elected? 

The candidates are 1,453, including 117 outgoing, who stand for this election by indirect ballot, proportional (departments with at least 3 senators) or majority vote for the others.

172 senators must be elected.

Are concerned 58 metropolitan departments (from Ain to Indre and from Bas-Rhin to the Territoire de Belfort, with the exception of Ile-de-France), Guyana as well as Wallis and Futuna, Saint-Barthélemy , Saint-Martin and French Polynesia.

What is at stake for the majority? 

The senatorial elections will logically be an extension of the municipal elections: after poor results in June, the group of 23 marchers may emerge weakened.

With an unknown: will their president François Patriat manage to save his seat in Côte d'Or?

Three seats are in play on a proportional basis.

The right should keep two and the third will be disputed between the former boss of the region and the socialist Colette Popard, a close friend of the mayor of Dijon François Rebsamen supported by a large part of the elected officials of the agglomeration.

Two ministers are also candidates: the ex-LR Sébastien Lecornu in the Eure and Jean-Baptiste Lemoyne in the Yonne. 

And for the other parties? 

On the side of environmentalists, boosted by the green wave of municipal elections, the challenge is to succeed in forming a group: ten senators are enough for that.

The Socialists, who regained their colors in June, hope to consolidate their position as the second group in the Luxembourg Palace, where the right should therefore remain the strongest, since it holds half of the cities of more than 9,000 inhabitants.

The major balances should not be upset, Sunday evening: allied to the centrists, Gérard Larcher has little to worry about for his re-election to the presidency of the Senate next Thursday.
