Very few politicians speak for ordinary people any more. Mostly, they speak to those with money in order to get some of that money for themselves. A shining example is Bernie Sanders. Recently, he was interviewed at length at Salon:

What I’ll tell you is what I do say in public, which is that, at a time when the middle class is collapsing; when we have more people living in poverty than ever before and we have huge income and wealth inequality; when we are the only major nation on earth that does not have a national healthcare system; when we have millions of young people leaving college deeply in debt; when we have the planetary crisis of climate change; when we, because of Citizens United, have a billionaire class now controlling our political process, we need candidates who are prepared to stand up without apology representing the working families of America and are prepared to take on the billionaire class which controls so much of America. I think that’s absolutely imperative that that takes place. What I have said is that I am giving thought to running for president. I haven’t made that decision. It’s a very, very difficult decision. I have gone to Iowa on a couple of vacations. I’ll be back there. I’ve gone to New Hampshire. I’ll be there this Saturday. And I’ve gone to other places in the country including the south—North Carolina, South Carolina, Alabama, Mississippi—to get a sense of how people are feeling. But yes, I am giving thought and I will make the decision at the appropriate time.
