Anybody, like Mitt Romney, who has such power and money behind them, will not be a candidate of conscience...but rather, that conscience, will be beholden to others. That's a very dangerous person to vote for because their words are idle and without meaning. Barack Obama may harbor principles that are entirely contrary to mine, but at least he has principles. Mitt Romney has none. He always was, and always will be, the quintessential political chameleon.
Who is behind Newt?
I understand that a couple of billionaires bought him a few years ago.
By contrast, Romney inherited a lot of money, and gave it away.
