The map below shows a hypothetical 5-district redistricting plan. Party X makes up 40% of all voters, distributed as shown. Based on how Party X's voters are grouped into districts, which redistricting technique does this map illustrate?
APacking — Party X voters are concentrated into a small number of districts, which Party X wins by large, wasted margins
BCracking — Party X voters are spread thinly across every district so that Party X never reaches a majority anywhere
CAnnexation — the district boundaries were redrawn to add new territory to an existing city
DMalapportionment — the five districts contain unequal total numbers of voters
Explanation
Party X's 10 precincts are concentrated into just 2 of the 5 districts, which Party X wins with a wasted 100% margin, while Party Y wins the other 3 districts comfortably — the defining pattern of packing, not cracking (which spreads a group thin instead of concentrating it), annexation, or malapportionment (every district here has the same number of precincts).
