Hm, I don't know - the added advantage is just 2.74%, well within the range one'd expect to ignore Goldschmidt's call if Bachelet makes a plea to them, while the hate between the two right-wingers can safely be predicted to eliminate even more from Piñera. And that's just the surface - also consider that by gaining absolute majority, the Centre-Left now won't have to rely on the hard left in the parliament, undermining a right-wing scare tactic that previously must have worked on some centrists - and Goldschmidt's declaration now only strenghtens that effect.
