Carlos, I don’t remember: could a former president run again after an intervening term, or was it one term in a lifetime?
A president in Argentina could be reelected one more term. (2 terms), Then he must wait one term to be a candidate again.
The problem that I note is that there are intermediate elections for representatives in the second year of a term, therefore the government tries to win again and is moved to a new electoral campaign, so it prevents to follow the advice of Machiavelli. (Do the evil at once, the good gradually). And many times a good government has to proceed in an unpopular way.
People do not like this, as it happens when your doctor tells you to stop eating, or stop smoking to recover your health.
In my personal mood, I prefer the hard things to be done now, however harsh and perhaps unbearable. But I was born a conservative and of course, not populist.
Duty is always before pleasure.
