This is from the arch-conservative Washington Examiner, so buyer beware. Questions about whether Biden’s losing it matter for obvious reasons, but the bigger picture is this: amidst a surge of young energy and a field crowded with people at the top of their game, the Dem power base has fallen behind a guy who in nine years (unless you want a one-term Dem) will be, well, nine years closer to losing it. The fights within the Democrats aren’t about left/center/right or multiculturalism, they’re about age. And the party’s core is solidly on the side of the olds.
