Argentina's centrist Provincias Unidas front is facing a difficult challenge in the midterm elections.
Their mission is to break through the polarisation of the ruling La Libertad Avanza alliance and the opposition Fuerza Patria coalition.
Its main goal, however, is to consolidate its position as a federal alternative to power and grow territorial roots for the future battles to come.
The outcome will clarify which of the six governors can break the polarisation in their respective provinces.
The Governors front could end up with a caucus of between 16 and 20 national deputies, a crucial number that could block or unblock legislation.
