The truth is that there shouldn't be one type of democratic party until people are ready to follow, together.
NYC is different from everywhere else in the US. Mandami is representing half of NYC. Half, the other half didn't vote for him. It is a tremendous win, neverthless. But, he has to deliver as mayor. I wish him the best, if he does well for New Yorkers, he will set an example for cities across the country.
Each Democrat needs to represent their constituency.
