As Larry observed, niceness may not be what's needed right now to take on Trump. That said, I liked Yang and his creative spirit and thinking outside the box.
Agree that Bernie, if he any real coalition building momentum would have crushed in NH. At some point the party will pick a point on the political spectrum... or it'll be a brokered convention.
What people need to do is look at polls, swallow some of their dreams, and realize that beating Trump involves acknowledging that nearly 60% of voters poll as not accepting a candidate generally characterized as socialist. The thing to do is get elected, repair some damage, and then try some trial balloons that don't make Susy and Bob Moderate clutch their pocketbooks in terror.
