Compared to the problematic closing of Peronist lists, the final agreement for the candidacies between La Libertad Avanza and the PRO ended up being much less contentious than what was anticipated for much of last week.

The analysis shortly after signing section by section was positive on both sides, with the Macri administration boasting about having ended up negotiating more places than it had imagined and downplaying the dismantling of mayors it suffered during the week: four of the 13 who signed left.

"We closed much better than we would have closed if we had gone separately from La Libertad Avanza," was the first reflection, which was repeated on Sunday, during the after-dinner conversation of many leaders who were exhausted after hours of debate about candidates and were only hoping to take an afternoon nap.

The calculation made by those close to Diego Santilli and Cristian Ritondo, the two main swords of Macri in the negotiation with the Mileísmo, is that they will put between eight and ten of their own legislators in the next Legislature, if the election of September 7 takes place in the terms they imagine.

Finally, Soledad Martínez remained within the alliance with the libertarians.

That number doubles the number projected if they had run from outside the party, with their own slate. And it's also higher than the number the Ritondists were excited about last Sunday, adding to the more than 150 councilors they would have nominated starting in December.

As an addition, Soledad Martínez, the mayor of Vicente López, did not leave, as she ended up closing a very favorable municipal list, 70/30 for Macri's party.

In a name-by-name briefing, the PRO party detailed the candidates with a chance of securing seats. Natalia Blanco and Alejandro Rabinovich, for the second electoral section; María Sotolano and Lucía Bontempo, for the third; Matías Ranzini, for the fourth; Guillermo Montenegro, for the fifth; Gustavo Coria, for the sixth; Ezequiel Galli, for the seventh; and Julieta Quintero Chasman, for the eighth.

However, it was confirmed that the balance of forces will be, in percentage terms, around 75-25 in favour of the libertarians and there was a latent feeling that the departures of four mayors have nourished forces that may be more competitive at the sectional level, such as Somos Buenos Aires, with radicalism and other parties coexisting there, Hechos, the force of the brothers Santiago and Manuel Passaglia, from San Nicolás, and Potencia, the space of María Eugenia Talerico.

Pablo Petrecca and María José Gentile, mayors of Junín and 9 de Julio, went to Somos, Javier Martínez, from Pergamino, will compete with the Passaglias, and Diego Reyes, from Puan, will go with the party of Talerico, former deputy head of the UIF.

In the PRO party, they also looked with a smile at the evident tensions that already exist between Somos and Hechos. Manuel Passaglia, a candidate for deputy for the latter, had to clarify that he is not a candidate for Somos, but for Hechos, and that they negotiated spaces with specific leaders, from Rojas and Pergamino.

I'm not the top of the Somos Buenos Aires list. Somos isn't competing in the second round. They should retract their position and apologize. But I doubt they will; they won't dare.

Section by section, the candidates

The libertarians and the PRO defined their candidates section by section, with the mayor of Tres de Febrero Diego Valenzuela as the main reference in the first section and the former commissioner Maximiliano Bondarenko in the third.

Behind the now libertarian Valenzuela, for a senate seat in the first section will go María Luz Bambaci and Luciano Olivera, who answer to Patricia Bullrich and Nicolás Pareja, respectively.

In the second section the candidates for deputies will be the ritondist Natalia Blanco, the parejista Pablo Morillo and the libertarian Analía Corvino.

In the third section, Sebastián Pareja placed the former police officer Bondarenko and Luis Ontiveros, while the novelty was María Sotolano as second, who answers to Jorge Macri, who had a rapprochement with the Mileis after the tensions and the fact that three of his own mayors left for other forces.

The fourth section is headed by the libertarian Gonzalo Cabezas, followed by the also mileísta Analía Balaudo and the ritondist Matías Ranzini as third.

The fifth section is headed by a strong man from the PRO like Guillermo Montenegro, mayor of General Pueyrredón, escorted by the couple member Cecilia Martínez and another libertarian like Matías de Urraza.

The sixth has Oscar Liberman, former libertarian mayoral candidate in Bahía Blanca, the Macrista lawyer Carla Pannelli and Héctor Gay, who was mayor of Bahía Blanca for two terms.

The seventh also goes to the Millenium party, with Alejandro Speroni as its candidate, followed by the also libertarian Celeste Arouxet and the former Macri mayor of Olavarría, Ezequiel Galli.

The eighth is finally completed by the libertarian Juan Osaba, Julieta Quintero Chasman, who comes from the PRO, and the brother of the presidential spokesman, Francisco Adorni.
