* Because Brazil was isolated in the UNO Security Counciil recently when old Lula committed the blunder to stick to a notoriously oppressive, undemocratic Turkish State abusing even of Torture, over Islamic Iran's chief, Mahmoud Ahmadinejad's Nuclear Bomb materials' controversy.
* Old Lula da Silva (forgetting all his previously critical positions when he was younger, in a sudden U-turn) astonishingly obeyed to USA's desiderara, and betrayed E.U., Russia, Australia, Developing and other Countries at UNO's Copenhagen Summit on Climate Change, contributing to its failure to take drastic measures to protect Natural Environment a gainst CO2 Pollution. To the point that, f.ex. the popular Australian Socialist f. Prime Minister Kevin Rudd never understood why this happened, and lost his job shortly afterwards, the Center-Right winning more votes.
* On the contrary, opposition leader José Serra is topically famous also for daring to oppose Multinational Pharmaceutic Companies in order to ensure Poor People's access to Medicine, thanks to generic drugs.
Being of Italian Family origin and having studied also in France, Serra could have better relations with Europe, while also keeping good relations with the USA where most of the brillant University career of this multi-Elected Brazilian Politician (son of a Poor immigrant) evolved, being apparently more adequat for a more Democratic, Multi-Polar World.
* Finally, it's not so important if a never elected "Technocrat" as Dilma Roussef (old Lula's successor) is favorable to Abortion, or not : At any case, she is for Genetic Manipulation of Human Embryos, which is even more Deadly and much more Dangerous....
Recent facts (comp. above) clearly show that she would persist, and probably aggravate, old Lula's strange U-turn towards a quasi-total alignement to the USA, (despite her Bulgarian origin), definitively droping, in real practice, any independently-minded, previous claim, (and thereby losing even any leadership among Latin American Nations)..
Initial Polls reportedly gave José Serra winning at a large margin, after attributing at Dilma Roussef a tie, and later-on a favorable edge But, if on this Sunday, Brazilian People refuse to give an absolute Majority to old Lula's collaborator, then, on the second round, at the end of the Month, Serra might not only broker a deal with the third, "Green" candidate, (f.ex. based on BioEthics, where PTD notoriously is pro-Technocrat, neglecting too much Human Values), but, more important, attract a growing number of Citizens which would go to vote if they saw that a Change is possible at the Horizon.
