Sebas, I don't know how long you've lived here and/or followed politics here, but there is no good answer to your question. Thus Thorsten's, and others', perhaps glib-seeming responses and what may seem like off-topic comments. But stated simply, the candidates are going to do and say whatever they will to get elected without being very specific. Scioli and Massa are going to take a populist road (which will include some form of currency/capital controls and may mean a train wreck in a year) and Macri will take a "business"-oriented approach (which, even if he is sincere in his desires may mean a wreck even quicker). No one can leave the currency controls where they are, they all seem to recognize it, but the only difference seems to be that the populist candidates don't want to let it go free and Macri thinks that if he lets everything go at once (including capital controls), the market-engine will magically start up and the peso won't lose value.
Personally, I think Macri has the right idea in the long run, but will probably screw things up with a shotgun approach in the short term if he gets in.
One thing I've learned from living here for nearly a decade is that it makes little difference what the players say, what intentions they have, what kind of logic one might try to apply to the situation given what they say. Things will almost certainly turn out different than you imagined.
My biggest question in all this is - which of these candidates has the most likely chance of getting done what they would want to do? I feel like the answer is "none of the above" unless their policies are close to what Cristina wants. This is because Cristina and her late husband have had over a decade to put into place a huge bureaucracy that is full of back-scratching deals and corruption, judges that are friendly to Cristina, and a majority in congress of her party members (at least right now - maybe that will change, but I doubt it, not yet anyway). All of this has allowed her to bend things more than any other candidate will be able to in my opinion and anyone who wants to really change things in ANY direction will be pushing against a lot of inertia. Scioli is the one who seems to be handed the keys, Massa doesn't have Cristina's blessings, and Macri is from the evil business camp, far from Cristina's policies.
Then, you have the whole voting thing to begin with. Choripan para todos y todas brings in the massive wave of the poor on Cristina's (Scioli's) side no matter what she does to the market-engine because too many think she's the second coming of Evita. And the voting machines - looks like a good possibility that those may be giving a Chavez-style election to Scioli, if you ask me.
Just sit back and watch the fun, because interpreting what the candidates are saying, translating that into a reality to come, and getting it right, is pretty much like winning the lottery.
I have yet to see a clear, succinct statement from any candidate as to what they intend to do, but then again I've been in the States for the last month and having not been following things that closely as a result. Maybe I've missed something.
