All that will happen is the Tory vote will collapse and some of those will go to Reform, thus reform will say it was a massive victory having started from zero while not actually changing the balance of power in Holyrood.
It was far more interesting when it looked like a real fight between 5 parties. Now it will be SNP with a handful of the others, greens might benefit from collapse in labour support but only if independance is somewhat sidelined.
