Should MacAllister abstain from voting?

The anti-recall campaign for Councilman McAllister accepted a $10,000 donation from Bill Dendy, the developer who wants to build a shopping center at the corner of Nutmeg and Jackson. Approval of this project is coming before the council for a vote tomorrow. I see a clear conflict of interest here; John Harper and Doug MacAllister, because of a semantics loophole, do not. What do you think; should he abstain from voting?
