Should first-past-the-post voting be abolished in the U.S.?

Added Apr 9, 2015

A first-past-the-post (abbreviated FPTP or FPP) election is one that is won by the candidate receiving more votes than any other(s). It is a common, but not universal, feature of electoral systems with single-member legislative districts, and generally results over time in a two-party competition. More: en.wikipedia.org.
