Given that his recent predecessors have performed so poorly in the job, he can hardly do any worse despite his lack of political experience.
Unlike them, he is not being burdened with unfair expectations that he is some kind of Superman who can instantly revive a party which came close to throttling itself.
Whyte was not active in Act during those ructions. He represents a clean break from its past - impossible for John Boscawen, the other candidate.
No doubt Boscawen would have been a safe pair of hands. But Act needs something or someone more inspiring to become relevant again.
Act needs to get back to basics, revisit its founding principles. It needs to put more space between itself and National. It needs to stop trying to be everything to everyone on the centre-right - behaviour that has created confusion about what Act stands for. It needs a fresh face to reinvigorate what remains of the membership and rebrand the party's public image for a wider audience. It needs someone with impeccable and uncompromising liberal credentials.
Whyte is that someone. He has one other thing going for him. National's election-year march to the political centre is ever accelerating, leaving ground ripe for Act to occupy.
But much depends on whether he can get Act into the media spotlight and keep it there. On that score, he will not lack for advice, given the allegiance to the party of some of the country's top political brains.
But Whyte is desperately short of time. He has nine months at most to rekindle enthusiasm in a party that rated zero in last night's 3 News poll.
