The full proportions of the debacle that awaits the Democrats next fall is starting to penetrate their complacent disdain and revulsion toward President Trump. Rank-and-file Democrats are so ecstatic at the arrival of a known candidate whose views on principal policy issues cannot be invoked by Republicans to frighten children into eating their breakfast cereal that they have accorded Joe Biden a levitation in the polls. Biden is a shopworn, moth-eaten, malapropistic journeyman about whom, when asked to assess him as a potential president, former bipartisan defense secretary and CIA director Robert Gates took four seconds to emit: “I don’t know.” In the land of the Ocasio-Cortez sound-alikes, a track-worn perennial candidate is king. Given how verbally accident-prone Biden has been throughout his nearly 50 years of public life, his present formidable lead in the polls against an immense field of candidates should be seen as the fulfilment of Democratic yearning for someone who would not alarm the voters in policy terms. The only other such candidate is the relatively unknown Amy Klobuchar. All Americans, even the president’s most strenuous supporters, should be comforted that the majority of Democrats can still think and count. It is a party infested with lunatics, but not controlled by them. This is in the same reassuring category as the Mueller investigation’s conclusion that no one in the United States colluded with Russians to influence the result of the 2016 election.
