Agree on Collado, as he represents, along with Faride and Paliza (and C. Mejía, by virtue of her present position, as well as Hipólito's daughter, with her dad being a powerbroker and extremely influential in many internal decisions) the future of the PRM, UNLESS, of course, he (Collado, that is) doesn't switch party allegiance, as some Dominican politicians are wont to do in search of better electoral odds.
Some of the other PRM stalwarts, such as Guido Gómez Mazara, Ramón Alburquerque, and Roberto Furcal may seek nomination but, in my opinion, their chances are slim to none, and Slim just left town.
