You know what's really lousy about the climate here on DU?

37. Not hard to believe. Once Bernie claimed the ideological purity ground.

We all want unicorns to be true.

Pointing out that the boring one is a better and smarter candidate than the unicorn salesman makes it look like you're criticizing unicorns.
This is similar to Bradly vs Gore in 2000. Bradly offered an unworkable but nice sounding health care promise. When Gore pointed out it was unrealistic, Gore was criticized.

On a personal level: people are lazy, we too often fall into ready made rhetoric rather than working out our own arguments. I've seen this happen with supporters of Palestinian rights using anti-Semitic rhetoric and now with Bernie supporters using racist rhetoric. I don't believe either camp is anti Semitic or racist, it's just easier to use pre made arguments.

The same is true for many Hillary supporters, sad to say. We fall into right wing rhetoric because its easier.

One avenue of argument I don't see from my fellow Hillary supporters is agreement. Yes single payer is nice but you know who would be great to get a public option? Hillary Clinton.

And if you want to go there you could attack Sanders supporters from the left. Single payer is a half way position, a national healthcare system is the way to go. Many of Sanders positions are not truly leftist anywhere, except America.

Finally you could just not argue. Research Clinton's positions and make a positive case for them. Probably not hard to do.
