Can Bernie Sanders Overtake Hillary?

Bernie Sanders has narrowed the fund raising gap with Hillary Clinton. She has taken in over the last three months $28 million to Sanders $24 million. While Clinton has been effectively targeted large donors, Sanders has set up and efficient online system for taking in more small donations. This puts Sanders ahead of what Barack Obama did in 2008 which bodes well for this seasoned politician. Do you think his system of gathering grass roots support and money can put Bernie Sanders ahead of Hillary Clinton?
