I don't see much need to narrow even a large candidate field, given a
decent election method. If you look at Approval's Condorcet and social
utility efficiencies compared to two-stage runoff, the gains from
switching to Approval could easily make up for the runoff's filtering
Think of the likely voter strategy in such a huge election-- voters
would simply refuse to approve unknown candidates (who would have been
eliminated in the first round of a traditional election), and instead
base their strategy around known candidates (e.g. approve of
better-than-average of the *known* candidates).
Although with a Condorcet method it might be helpful to narrow the field
first to some manageable number, so that voters can intelligently rank
the remaining candidates. :)

I would rather take the high road, and point out the fallacies involved
in trying to guarantee a so-called "majority winner". I consider the
term meaningless in elections with three or more candidates.

I agree, although this would also be true of non-partisan first round

I disagree with this conclusion, at least with qualifications. I see
two basic "flavors" of non-partisan local election: the high-visibility
races for supervisor, mayor, etc., and the low-visibility races for such
offices as county tax assessor or public defender. The latter rarely
have more than two or three candidates running, and when a runoff when
required tends to be viewed as a waste of everybody's time (candidates
included) since the turnout is often very low.
I think one of these minor races was actually a trigger for San
Francisco adopting IRV-- that and the fact that SF's runoffs were held
as special elections a few weeks after the first round (they didn't
schedule the two rounds to coincide with the primary and general
elections, the way most counties do), so that SF runoffs were Expensive.
My point is that for these minor elections, there is often considerable
desire to get rid of the runoffs. These minor elections are also the
logical choice for any pilot programs to implement Approval. Keeping
the runoff in place would negate one of the biggest reasons for making
