The popularity of Argentina's President Cristina Fernandez has fallen to 30% from 64% a year earlier. The issues appear to be unhappiness over street crime, high inflation and unemployment. See the Reuters article for details.
When this happens in Argentina, there is often a military coup after which the former president goes to live in Spain. Paradoxically, if unpopular Fernandez can finish out her term, it will be a good sign for representative government in Argentina.
