Philippa Baker-Hogan has already been accused of "electioneering" this year as she has sought to distance herself from Ms Main and turn a bit of heat on the mayor.
And Jack Bullock has also indicated some ambition to lead the district one day, though a rather chequered last two years might see him bide his time.
Both those two councillors have strong support, both polling over 8000 votes at the last poll.
And, of course, there could always be a not-so-dark horse waiting in the wings.
Other council speculation suggests some of the sitting members may follow Ms Main and farewell the chamber, while on the outside there are a few people jostling for position.
As always in politics, in a few months' time today's conclusions may not seem so foregone.
