Our current election system guarantees that there will be minorities
in every district who remain unrepresented by someone with their political
views. District lines can be drawn either to shut out minority voices
or strengthen them — A process called "gerrymandering." As
this game illustrates, the way in which district lines are drawn has
a great effect on who wins representation in Single-Member District,
Winner-Take-All elections.

Below is a map of the political geography of a typical city. There are
40 Democrats (D) concentrated in the center and 32 Republicans (R) dominating
the suburbs. Our current winner-take-all election system divides such
areas up into districts, each represented by a single elected official.
The city pictured must be divided into four districts, each with six "neighborhoods" (a
cluster of three letters).

First, imagine how to draw district lines to create a district plan
which gives Republicans a strong advantage over Democrats. (Hint: The
tactic known as "packing," in which strongly partisan areas
are packed into a single district, should be used here.)

Next, create a district plan where the Democrats have the advantage.
(Hint: "Crack" the Republicans among several districts.)
