Exactly. As a Brazilian, Paulista and Paulistano I also second this.
I find strange that: 1) corruption in Brazil, for these people, has just begun on January 1st, 2003 (when PT started their government) and 2) the corrupt people only are on PT and not on PSDB/DEM/name your right-wing party. Meanwhile, here on Sao Paulo state (where the same political group holds the power since 1982), we got massive corruption schemas that were never investigated: the Alston train affair, the irresponsible water management of Sao Paulo's metro area (look for "draught" and "Cantareira") and, last but not least, the case of school meals ("merenda") affair, where the food for the classmates has been sent everywhere but state schools. Mind you, the food that should had been sent to schools has been found at a deposit on a barbecue restaurant of Jundiaí (a city ~50 km from Sao Paulo).
Moreover, the opponent of the right-wing coalition which lost the presidential elections in 2014 has also been denounced on the very same operation that is targeting Lula nowadays not less than 5 times by 5 different people, and absolutely nothing has been done against him. He has also his share of scandals to be investigated - for example, an airport built besides his farm with state money - but the media just does not give a fsck about it. Dilma's government is mediocre at best, but Aecio and his party (PSDB) have been very keen on putting out the fire with gasoline.
