The party certainly needs some reform in terms of its positions. For victories in the 2018 midterm elections, we will need a truly united and energized party. That's not going to happen if Bernie continues to criticize party members and attempt to gain control without joining the party.

That won't sit well with Dems who do a lot of the organizing and hard grunt work. Anyone who tries to control the direction of the party but will not join the party, will not be successful. Two many Dems won't accept it.

It is galling to too many that a guy who wants to run the party, does not see the party as worthy of his membership. It's certainly galling to me.
