Answer

Answer key: Electoral College worksheet

1. Outcome: No one has 270 yet
1. Add the electoral votes of the states given to Candidate A (AK 3, DC 3, IN 11, IA 6, KS 6, LA 8, ME-1 1, NE-3 1, NH 4, PA 19, SD 3, WY 3).
  $3 + 3 + 11 + 6 + 6 + 8 + 1 + 1 + 4 + 19 + 3 + 3$ $= 68$
2. Add the electoral votes of the states given to Candidate B (CA 54, GA 16, ME-AL 2, MD 10, MN 10, MO 10, NE-1 1, NE-2 1, NM 5, NY 28, OR 8, RI 4, WV 4, WI 10).
  $54 + 16 + 2 + 10 + 10 + 10 + 1 + 1 + 5 + 28 + 8 + 4 + 4 + 10$ $= 163$
3. Any vote not given to a candidate is undecided, so subtract both totals from all 538 electoral votes.
  $538 - 68 - 163$ $= 307$
4. To reach 270, Candidate A needs 270 minus 68 more votes, out of the 307 still undecided.
  $270 - 68$ $= 202$
5. To reach 270, Candidate B needs 270 minus 163 more votes, out of the 307 still undecided.
  $270 - 163$ $= 107$
6. A candidate needs 270 of the 538 electoral votes, a majority, to win. Compare each total with 270.
  $No one has 270 yet$
2. Outcome: Candidate B reaches 270
1. Add the electoral votes of the states given to Candidate A (DE 3, DC 3, FL 30, IN 11, LA 8, ME-1 1, MT 4, NE-AL 2, NE-3 1, NH 4, NJ 14, NC 16, OK 7, PA 19, SC 9, UT 6, WA 12, WY 3).
  $3 + 3 + 30 + 11 + 8 + 1 + 4 + 2 + 1 + 4 + 14 + 16 + 7 + 19 + 9 + 6 + 12 + 3$ $= 153$
2. Add the electoral votes of the states given to Candidate B (AZ 11, AR 6, CA 54, CO 10, GA 16, HI 4, ID 4, KY 8, ME-AL 2, MD 10, MN 10, MS 6, MO 10, NE-1 1, NV 6, NM 5, NY 28, TN 11, TX 40, VT 3, VA 13, WV 4, WI 10).
  $11 + 6 + 54 + 10 + 16 + 4 + 4 + 8 + 2 + 10 + 10 + 6 + 10 + 1 + 6 + 5 + 28 + 11 + 40 + 3 + 13 + 4 + 10$ $= 272$
3. Any vote not given to a candidate is undecided, so subtract both totals from all 538 electoral votes.
  $538 - 153 - 272$ $= 113$
4. Candidate A needs 270 minus 153. That is more than the 113 undecided votes, so Candidate A can no longer reach 270.
  $270 - 153$ $= 117$
5. Candidate B has 272. That is at least 270, a majority of 538, so Candidate B needs no more.
  $272 \geq 270$
6. A candidate needs 270 of the 538 electoral votes, a majority, to win. Compare each total with 270.
  $Candidate B reaches 270$
3. Outcome: No one has 270 yet

  $9 + 3 + 7 + 3 + 3 + 30 + 11 + 6 + 6 + 8 + 1 + 11 + 4 + 2 + 1 + 4 + 14 + 16 + 3 + 17 + 7 + 19 + 9 + 3 + 12 + 3$ $= 212$

  $11 + 6 + 54 + 16 + 4 + 8 + 2 + 1 + 10 + 10 + 1 + 1 + 6 + 5 + 28 + 8 + 4 + 11 + 40 + 3 + 13$ $= 242$
3. Any vote not given to a candidate is undecided, so subtract both totals from all 538 electoral votes.
  $538 - 212 - 242$ $= 84$
4. To reach 270, Candidate A needs 270 minus 212 more votes, out of the 84 still undecided.
  $270 - 212$ $= 58$
5. To reach 270, Candidate B needs 270 minus 242 more votes, out of the 84 still undecided.
  $270 - 242$ $= 28$
6. A candidate needs 270 of the 538 electoral votes, a majority, to win. Compare each total with 270.
  $No one has 270 yet$

  $10 + 4 + 4 + 19 + 8 + 2 + 10 + 10 + 1 + 6 + 28 + 8 + 4 + 40 + 13 + 4 + 10$ $= 181$
3. Any vote not given to a candidate is undecided, so subtract both totals from all 538 electoral votes.
  $538 - 68 - 181$ $= 289$
4. To reach 270, Candidate A needs 270 minus 68 more votes, out of the 289 still undecided.
  $270 - 68$ $= 202$
5. To reach 270, Candidate B needs 270 minus 181 more votes, out of the 289 still undecided.
  $270 - 181$ $= 89$
