a candidate for whom I have volunteered and supported monetarily

anybody I know? (probably not)

I've never gone to a primary party before. Is the food good?

I've never been to a primary party myself so no idea.

Admittedly, I have been to a few dinner-type fundraisers and those have all been edible at least -- I imagine there's a balance one has to strike in that the food has to be good enough that one thinks well of the candidate and the event, but not so good that you get the impression that one's money is going towards food rather than the campaign.
