his stances on militarism, trade etc. are what I am talking about.

You can try to ignore them but the people who think these issues are central are very much alive and well.
You can dis the idea of a third party all you like, but there will no doubt be even stronger efforts for a progressive party unless these issues are adequately addressed.
People are not just going to go away and give up.
I am just speaking from what I have observed from speaking with many 'progressives'. If you don't want this to happen then work to get these voices some traction in the party.
