Plausible deniability vs. undeniable implausibility

We all know what plausible deniability is. It’s when somebody does a dirty, but has a plausible alibi. For example, when those Nordstream pipelines mysteriously exploded, all eyes immediately turned to DC. But DC had several alibis in the can, ready to go. They ranged from low plausibility ( the Rooskies blew up their own pipeline) to quite plausible yarns (Ukrainian operatives renting a yacht). Our curiously incurious media sniffed plausible deniability, and left it at that. No need to further investigate this horrendous crime against the environment, not to mention a devastating terrorist attack on the critical infrastructure of a US ally. Then there’s undeniable implausibility. Anyone who watched the debate of the century last night knows there’s no plausible possibility that mumbling, rambling, vacuous, shell of a President Biden is the person executing the executive functions of his office. This is a problem for the folks operating America’s Democracy Theatre. There’s always room for a wee flourish of fantasy in any theatrical production, of course, but trotting out Dementia Joe for a debate with Donny J, a seasoned stage pro who made hundreds of millions in reality TV? That’s just elder abuse!
