SOURCE/LINK: http://www.bbc.com/news/blogs/trending/Mark Ruffalo- the Hollywood actor best known for playing the Hulk - has waded intoBrazilian politics to endorse a presidential candidate, only to reverse hisposition the following day.The Hulk actor isn't a regular pundit on South American electoral races. But onSunday he chose to join the debate in Brazil, kick-starting an unusual chain ofevents that played out over social media."Marina Silva isprobably one of the most interesting and exciting politicians on the worldstage today," he said in a YouTube video, endorsing the presidential candidate.The video touched a nervewith legions of gay rights campaigners in Brazil. They started tweeting Ruffalourging him not to back a candidate they said did not support gay marriage."I hope you're just misinformed. Read more about it please," askedone.Ruffalo soon replied."Thank you, I am looking into it. I can not support a homophobic," he said, and asked Silva directly on Twitter: "Are you pro marriage equality?"An aide tweeted back fromher account to say that she was, posting a link to her manifesto which pledges support for they gay community. But many of herpolitical opponents chose to keep the conversation going. "Nope," and "NAO," they tweeted back. Some claimed that they doubted the manifesto reflected her true intentions. Theactor's name began trending in Brazil, and has appeared some 20,000 times inthe last two days.Eventually, Ruffalodeclared his position. "It has come to my attention that the BrazilianCandidate for President, Marina Silva, may be against gay marriage... It is alittle bit murky and unclear presently," he said on his Tumblr blog. "I have to apologise for not doing abetter job of vetting this decision." Until Silva clarified her views, hewrote, "my support is null and void."Silva is one of three leadingcandidates for the presidency in Sunday's election. Born into a poverty in asmall village, she worked on a rubber tree plantation and as a housemaid beforemaking her way into politics. She hopes to usurp the country's currentpresident - Dilma Rousseff - whose incumbent left-wing Workers Party has heldpower for almost 12 years, but has recently been beset by a string ofcorruption scandals. Along with Aecio Neves - who leads the centrist PSDB party- all the candidates have signalled their support for gay rights, though doubtsremain about whether they will prioritise the issue after the election.Reporting by Sam Judah and Bruno GarcezYou canfollow BBC Trending on Twitter @BBCtrendingAll ourstories are at bbc.com/trending SOURCE/LINIK:http://ataqueaberto.blogspot.com.br/2014/10/carta-aberta-ao-senhor-senador-e.htmlCARTA ABERTA AO SENADOR E CANDIDATO A PRESIDENCIADA REPUBLICA, AECIO NEVES DA CUNHAExmo.Sr.Senador Aecio Neves,Aocumprimenta-lo pela passagem para o segundo turno das eleicoes venho,representando os 14.000 membros do Grupo de Facebook Inglourious Doctor,declarar abertamente nosso apoio ao senhor numa campanha em que tera como adversarioo retrato do mal em si.Sabemos,senador Aecio, que muito mais do que o cargo para presidente, e o futuro daspessoas de bem que agora se encontra em jogo no Brasil.
