From a Wall Street Journal column by Kimberley A. Strassel headlined “Democrats Discover the Age Issue”:

Nothing is certain but death and taxes, save perhaps Democrats’ recent ability to ignore the relevance of old age to that saying. Will their Dianne Feinstein problem provoke a rethink of the wisdom of renominating Joe Biden?

Ms. Feinstein, California’s 89-year-old senior senator, announced this week that her return to Washington would be delayed by “continued complications” of shingles. She has already missed nearly three-quarters of Senate votes this year because of her illness, though Democrats’ more immediate frustration is that her absence leaves the Judiciary Committee deadlocked, unable to greenlight Mr. Biden’s nominees. With the House in GOP hands, that’s about all the Senate is currently good for.
