There is nothing inevitable about Bernie Sanders winning the Democratic Party nomination and the 2016 Presidential election. He is not an heir to a political dynasty. He was supported by no more than 2 percent of the American voting public as recently as ten months ago. As I write, he remains behind Secretary Clinton in delegate counts.

However, he has risen in the polls, has won in the primary in seven states and counting, and is leading a growing movement anchored in the support of younger voters. Bernie Sanders is drawing support, primarily because he has a big idea – a critical perspective on what is wrong with American democratic governance.

He has put his finger on the undue influence of wealth on the conduct and outcome of elections. In line with other sophisticated analysts of our political system, such as Lawrence Lessig, he focuses our attention on the need for campaign finance reform, as one major means for addressing this problem.

This idea is central as it explains many other problems and issues. Rather than forming ad hoc, ‘whack a mole’ policy responses to a litany of issues, he has put his focus on a coherent explanation for why so many other issues are emerging.

That is why he continually brings debate back to this root explanation for many problems, even though it opens him up to superficial but false allegations of him being a single issue candidate. Not so. He has clear and compelling positions on all of the issues.

Is he too radical? Is he extreme in being a Democratic Socialist? No. Listen to him, and what he means by his philosophy. First, he wants free tuition for college students. Extreme? He argues that a college education today is equivalent to having a high school education in decades past. Public high school educations are tuition free in the United States, as they are funded by taxes, and he is simply extending this model to college – the new high school. This does not mean that high school education is not in need of greater support and reform. A quite funny refrain in England, is that you can get a good high school education in the US, but you have to go to college to get it. But that is another reason for extending public support to college, as is done in many countries across Europe, and not putting so many students in such great financial debt before they even begin their careers.

Is he too radical for calling for a greater redistribution of wealth? Nearly all taxes tend to be progressive and redistribute wealth. What he is saying is that the US has drifted into a period of sever income inequality, when the top one percent of households, about 1.4 million households, have benefitted far more in our economy than the bottom 99 percent. But its even worse. The top of the top one percent have benefitted dramatically more than the others among the one percent. Senator Sanders is arguing that the top one percent is not currently paying their fair share of taxes, and that they should. That is not extreme, or a radical idea. It is a progressive idea in the best sense of that word, adapted to the circumstances of today.

Is he inexperienced? No. Senator Sanders has held public offices for over thirty years. He is more experienced in holding an elected public office, as a Mayor, Representative, and then Senator, than any other candidate in either party that is running for president.

Finally, will he be fit as a Commander in Chief. As Senator Sanders argues, he has been on the right side of major decisions. He was opposed to the invasion of Iraq in 2003, when this was not a popular position in the US. Judgement is perhaps the most important quality of a prospective commander in chief.

I don’t agree with every position Senator Sanders has taken on every issue. For example, I am more supportive of reducing trade barriers, and not erecting greater barriers to international trade, but his discussion of trade initiatives in tonight’s CNN Debate is leading me to reconsider my position. Bernie Sanders is clear-headed, thoughtful, and focused on central issues for strengthening our democratic system, primarily through campaign finance reform.

There is no more important issue that the vitality of our democracy, and the extreme inequalities in wealth emerging and its impact on campaign financing, because these trends threaten to undermine the vitality of our democracy. Given the issues arising over infrastructure, immigration, jobs, and more, we certainly need a healthy, functional and stable democratic system for discussing these conflicts, and making decisions. This is where Senator Sanders – his ideas, demeanor and experience – will have real payoffs.

I attended his recent rally in East Lansing, Michigan, at Michigan State University. Two to three thousand were expected, but over ten thousand came to the rally. Being there and seeing the enthusiasm of such a diverse array of younger voters was one of the most encouraging political moments I’ve had in recent years. They see a promising vision for their future. They and we need a person with a vision of what needs to be done in the coming decades, not what can be done in the next few years. As others have found, you might well discover that Bernie is indeed the ‘real thing’.
