BUENOS AIRES (Reuters) - Argentina's election race is narrowing into a two-horse race, polling ahead of the Aug. 13 primary vote shows, with the ruling Peronist coalition's choice of a centrist candidate defusing some of the threat from far-right libertarian Javier Milei.

Pollsters have the main conservative opposition bloc's top two candidates, ex-Security Minister Patricia Bullrich and Buenos Aires Mayor Horacio Larreta, just ahead of the ruling coalition runner, Economy Minister Sergio Massa.
