Joe Biden winning the presidency may turn out very badly for the Democratic Party because success obscures problems that need fixing. If we’re winning, it’s working, the thinking goes, so there can’t be much wrong with what we’re doing.

This is delusional. Making Donald Trump a one-term president seems to have ended any real effort by Democrats to stop treating ordinary people as ignorant plebs. This is unwise if you want their votes and will probably come back and bite the party as election cycles roll on.
