To become president, a candidate must win 270 of the total of 538 votes in the Electoral College. Chance (Winter 2010) demonstrated the impact on the presidential election of winning California. Assuming a candidate wins California’s 55 votes, the number of additional Electoral College votes the candidate will win can be approximated by a
