Mar was the only one of the six candidates speaking at a noon-hour debate who said he might consider a provincial vote this year.
Candidate Ted Morton said he wouldn't take that route because the next premier needs to show Albertans a budget and detail other priorities first.
Alison Redford and Rick Orman agreed, with Orman saying a throne speech and a budget would give Albertans a clear understanding of the new leader.
Doug Horner said the party needs time to unite behind its new boss and set long-term action plans.
Doug Griffiths said the election should go ahead in 2012 and anything earlier would be cheating voters.
