Former Vice President Biden is the personification of the decrepit and
right-wing character of the Democratic Party. In the past 10 days alone,
Biden has declared himself a candidate for the US Senate, rather than
president, confused his wife and his sister as they stood on either side
of him, called himself an “Obiden Bama Democrat,” and declared that 150
million Americans died in gun violence over the past decade. This is
not just a matter of Biden’s declining mental state: it is the
Democratic Party, not just its presidential frontrunner, that is verging
on political senility.
