@revelette2,
Your source is a blog and a private opinion, just like ours.
Bernie has won already! He came 9 months ago into the ring as a virtual nobody and he has made it without donations of corporate America, without lobbyists standing behind him and without the NRA. He came with an honest approach, with money from pivate people, and he is giving Americans hope that there is more to politics than just greed, power and their own enrichment of funds.
To get this far ahead in Iowa to be neck on neck with a career politician like Hilary Clinton whose promises are by far the most outrageous (in the Democratic field), is quite remarkable for Sanders. He's got practically no media coverage other than social media by individuals, every stone that is placed in his way he's climbed over and he managed to get young voters excited to not only vote for him, but to believe in a better future for them.
Iowans have shown already what America will show in the months to come - that we need a change in the same old, same old manipulative, stagnating and contra productive society of greed in politics.
