I will vote for the Democratic nominee, but this kind of stuff is an admission of defeat and tells me that the candidate in question should bow out now. I don't know how else to read it. "If we substitute some other metric for the actual way we do things, clearly my candidate would win!"
Quit it. If your campaign has now conceded there's no way to win, it's time to drop out.
And again: I will vote for the eventual nominee, so if that isn't what the campaign is saying, feel free. But if there's no way for Candidate A to win at this late date, Candidate A should withdraw.
