Reapportionment & Redistricting For the House of Representatives
In the Senate, every state gets represented by 2 senators regardless of population • In the House of Representatives, representation is based on population…
Every 10 years the Census Bureau counts the population • The population of each state determines the number of representatives in the House to which each state is entitled • This process is called Reapportionment
After reapportionment, state legislatures set up congressional districts—one for each representative in the House • This process of setting up new district lines is called Redistricting
The population in each congressional district must be about the same—currently around 700,000 people in each district • Districts must be compact and contiguous • Whichever political party controls the state legislature controls redistricting
Gerrymandering • Controlling parties often use this power by --drawing district boundaries to gain an advantage in elections • The goal is to send as many representatives from your party to the House as possible
“Packing” • including as many of the opponent’s voters as possible into one district • This weakens the opposing party by combining many similar votes into one voting block, opening up the other blocks for the minority party.
EXAMPLE of PACKING Six districts: A, B, C, D, E, F Two parties : X and Y 100 voters.Majority in a district wins the district.X has 60 % of the voters.Y has 40 % of the voters.-X has a majority of support in the population, but Y has the legislative majority. - Y has the power to draw the district boundaries.District Allocation:A: 26 Voters from X, 1 from Y. (X wins district A)B: 2 Voters from X, 10 from Y. (Y wins district B)C: 2 Voters from X, 10 from Y. (Y wins district C)D: 26 Voters from X, 1 from Y, (X wins district D) E: 2 Voters from X, 10 from Y. (Y wins district E) F: 2 Voters from X, 10 from Y. (Y wins district F) Results :TWO THIRDS of the legislative seats go to the minority party Y.
“Cracking” • dividing an opponent’s voters into many different districts • This weakens the opposing party by spreading the vote out so they can overruled by the majority party.
