Precisely. Even if the only goal is winning, the Dems need to recognise that demographic clout in the electorate is shifting from Boomers to Millenials and that they have to consider the latter’s priorities at least as much as the former’s.
The age of the politicians or officials themselves doesn’t matter as long as they’re willing to adapt and be straight with young people about how they’ve been screwed over by older generations on everything from the environment to the economy to the future of liberal democracy. RBG gets it and so does Sanders – that’s why young people consider them both cool even though they’re both grumpy olds.
