In 2008, no one thought that Obama would beat Hillary. The rest is history.
Because Hillary comes across as person who is not very honest and has a sleazy husband, she is very vulnerable right now. But she is also the strong candidate of the Democratic establishment and they will spend billions of dollars to defeat Bernie.
All those who are registered as NPA's should consider changing their voting registration temporarily and voting for Bernie in the primaries.
If there is a Trump vs Hillary in 2016, I will stay home.
