Elected politicians pay little if any attention to the political party "platforms" selected by political activists at party conventions. These platforms routinely make little concession to the politically possible, and in that respect they represent aspirational goals. Of course they also reflect as well as anything what The People actually want and would like to see their elected Politicians trying to achieve as closely as possible. If only wishes were horses.
Unfortunately, the Very Serious Presidential Candidate Hillary Clinton and her backers and others have been sucked into not even permitting a place for hope if it conflicts with what The Candidate wants.
This is one more case of where the party machinery needs to get voter discipline by seeing a loss, at least of unnecessary votes in uncontested states.
I am not for abandoning the Democratic Party, but for making the Democratic Party Great Again!
