Very similar to (but probably more ridiculous than)
vote splitting is the spoiler
effect.
The result of all this is that FPTP bodies tend towards dual party systems after a while; the similar candidates fight it out in primaries so that in the real election, there's only two major choices and the
effect of
vote splitting is minimized.
The aim of this is to reduce the
effect of
split votes and maximizing their chance of removing the incumbent representative.
Admittedly, while the minor party is small (and hence eliminated in the first few rounds) this
effect doesn't show up, unlike under plurality where minor parties are always a
vote -
splitting force.
