/*
CSE 303, Spring 2009, Marty Stepp
This program reads a file of state-by-state 2008 presidential election polls,
where each line contains a state code, percent votes for Obama/McCain, and number
of electoral votes for that state:

AL 34 54 9
AK 42 53 3
AZ 41 49 10

and outputs how many total electoral votes each candidate earned.
