That's because there's such a large wage discrepancy that most folk in the country are too poor to have to pay taxes. Mitt Romney does not support the middle class, nor does he seem even capable or relating to them. His flip-flopping is ridiculously rapid and opportunistic.
His religion officially believed that black people were inferior until 1978 - he was an adult and member of the LDS at that point.
He is the only presidential candidate in decades to fail to release his tax returns in their entirety to the public and he admits to having several offshore accounts in the Cayman islands.
He outsourced thousands of jobs during his time at Bain Capitol, a trend that company continues in even now during his campaign.
For tax purposes, He claimed to retire from his position as CEO with Bain in 1999, but documents signed by him as CEO in 2002 are on file with SEC which is fraud.
He refuses to admit that people die due to lack of healthcare.
He said he wants monetary incentives to accomplish goals as president.
He got Billy Graham to endorse him, effectively destroying the separation of church and state. Shame on Graham too.
His campaign contributions have majoritively come from a few very select wealthy businessmen, not people like you and me. He doesn't and won't represent our interests.
Do not take this as a pro-Obama post by any means. We are very much in a "Douche and Turd Sandwich" situation.
