and having no core, as the OP does, but not for using her "flexible" campaign positions as disingenuous marketing tools to get her quite solid corporatist core elected, because they're part of the same core and do the same thing but feigning the other side of the carefully filtered campaign issues.

And it's good to notice how the corporatist intersection of the two parties is precisely where the approved punditry always suggests the serious politicians will unite to "get things done".

We don't want, or need, those things done. Their whole game is to narrow down that intersection to corporate interests so that's all that can be accomplished with bipartisanship (TPP, Heritage/Romney/Obamacare, entitlement "reform", austerity programs for the 99% liquidity programs for the "job creators", military adventurism to guarantee corporate access to global resources, etc etc).

Bernie's aware of this. To some extent he is part of the same old game, but to a smaller extent than any other serious candidate in recent memory. He will seek out common ground and ways to get things done outside of that corporatist intersection between the parties. Increasingly, there is oppportunity on the right wing (citizens more than politicians, but that's where it starts) to be receptive to such, and Bernie is exactly the right person to lead this.
