As a starting point, try using Nick Cox's -majority- routine, downloadable
by SSC for just this purpose (-findit majority-). An example:
. majority votesD votesA, pos(votesD) neg(votesA) by(state) [percent]
generate(combo1)
I say "starting point", because -majority- can only handle two parties at
once: and even then in a particular combination.
By the way, please use informative subject titles when posting to
Statalist. :)
