Why isn't Dennis Kucinich winning?? I think his ideas are leaps & bounds above all of the other democratics

I think pound for pound Dennis Kucinich has better ideas and solutions than any of the democratic front runners. I also think he understand the constitution far better than any of them. I am baffled as to why he isn't even recognized in most national postings of the top polls. Is it just me or do people truly think that Hillary, Obama, Edwards, and Richardson are really better than Dennis Kucinich???
