Well the President, Sebastian Piñera, certainly has been in for a rough ride in the polls. After a dramatic and successful rescue effort saw the emergence of 33 trapped miners in October 2010 his popularity spiked. Sadly for the beleaguered leader, his popularity has taken a slide for pretty much every successive month after that. Student protests against fees and opposition to the Hydroelectric power project in Aysén, Patagonia are just some of the lowlights in the Billionaire’s term. Perhaps he is simply out of touch with the expectations that Chileans have for their country in this emerging new dawn for South America, or perhaps the right-wing party has simply leaned too far right and too close to a rampant capitalist model that is being rejected by many across the world. Chile has certainly suffered an increase in inequality over recent years. The graph below charts the demise of Piñera in the polls and his cabinet along with him. In fact not all have been tarred with the same brush and of those minsters presented here several are doing quite well in the perceptions game. So, what to do now? How about ditching the figure head? Well that red line is baulking southwards and appears to be separating from the herd!

Original data collected by Adimark included only ministers who were recognised by more than 40% of respondents. Here we present only those with full data for the period May 2010 to April 2012.

Ah what the hell, let’s do a t-test :)… Yep, Piñera’s average over this time period is significantly worse than the Grand average of all the other ministers combined (p = 0.0000573). For the geeks that’s a two-tailed t-test with an assumption of unequal variances. Not shown in the figure but included in the comparison were ministers Carolina Schmidt (National Service for Women), Andrés Allamand (Defense Minister), Evelyn Matthei (Minister of Labour), Pablo Langueira (Minister of Economy), Andrés Chadwick (General Secretary to the Government), Pedro Pablo Errázuriz (Minister of Transport and Telecommunications) and Harold Beyer (Minister of Education).
