Macri’s macro: what is next?

It finally happened: Macri is now president, though the difference in the final count of the election was of only 2.8 percentage points over Scioli; much tighter than had been predicted by the opinion polls.  Does this small difference hamper Macri’s ability to govern? A landslide victory would have certainly been better for him, though initially he seems to have the support from a large part of the opposition (including some Peronists) while he is making progress in building a coalition to move ahead with his plan and pass the necessary laws during the first few months.
