Quite a buzz is in the news in respect of today’s 50th anniversary of President Ford pardoning President Nixon. The talk under way is over whether President Biden — or, if she wins, Kamala Harris — should pardon Mr. Biden’s son and, in President Trump, his predecessor. Or, should President Trump win a second term, whether he should pardon Messrs. Biden. The Sun, we’ve marked, is in favor of pardoning the whole lot of them — and more to boot.
