It seems generally true in the English-speaking world that very successful politicians are creatures of uncanny memory — and, as perhaps a consequence, they are often superpowered holders of grudges that can last generations. That’s one thing that makes Wednesday’s sudden, eruptive reunion between the triumphant BC Conservatives and the collapsing BC United Party so extraordinary. John Rustad was ushered out of the caucus of not-yet-United BC Liberals almost exactly two years ago, and since that moment, he and United leader Kevin Falcon have been locked in unrelenting mongoose-vs.-cobra personal combat.
