The Democratic Party platform reflects the position of the party for four years and is voted on and influenced by all delegates (including delegates for candidates that do not win, ex. Bernie's delegates the past two elections).

A page on the Obama administration website reflected the personal opinion of the president at the time it was posted, and can be changed at any time.

The presidential nominee is not necessarily going to agree with the party platform (although they are more or less telling voters they will uphold it). The party and all of its delegates certainly need not agree with everything the president says.

Exactly. The party's official platform is equally dismissible as - if not more dismissible than - as the actions taken by the party in recent history, right?

I think it’s fair to ask people to read past the headline to get the whole story.

Sure. I'm asking people to read between the lines, because they are conspicuously absent of a groundbreaking shift in the politics of nuclear energy.
