Once again, zero evidence of mischievous crossover voting having an impact

There's about as much evidence for substantial mischievous crossover voting in open primaries as there is for voter fraud in general elections.

Like voter fraud, mischievous crossover voting merely serves as a ready-made excuse for supporters of a particular candidate.

Still, I'm sure we'll be hearing the same preemptive excuse-making in another 4 or 8 years, as we do every primary season. Que será, será.
