BOISE -- The latest polls show a close race for president on Election Day, and a chance for an outcome that's only happened a few times.
Some analysts say it also brings about more controversy over the Electoral College.
On Tuesday, when you cast your ballot, it could be the elector in your state who picks the president. That's because it's shaping up to be a historic race between Mitt Romney and Barack Obama, calling even more attention to the group designed by the Constitution to chose the correct candidate -- the Electoral College.
In Idaho, this election, it looks like the four men and women will be supporting Romney. Political Analyst Dr. David Adler says, "These are faithful, abiding Republicans, rewarded for their long service to the party."
It's a long standing process as well, one that our founding fathers struggled with. Adler says those delegates to the Constitution wanted a compromise between the government and the voters.
The Electoral College was formed so that those individuals from each state who knew each candidate well, could weigh in.
In 2012, those 538 electors could mean a historic outcome.
"There's a fairly decent chance that Obama would win the Electoral College and Romney would win the popular vote, and he (Romney) would win the popular vote because voters in red states will turn out and he'll get lots of votes," said Adler.
It all boils down to which states hold the most electoral votes. For example in Idaho, if Romney wins the popular vote, all four electoral votes would go to him.
Those votes are based on population. While Idaho has just 4 electoral votes, Colorado has 9, Oregon has 7, and California a whopping 55, more than 13 times the number in Idaho.
"When we think about this, even though we are selecting the president, in reality we have 50 state presidential elections," said Adler.
Mitt Romney's electors in Idaho are Travis Hawkes, Teresa Luna, Jason Risch and Damond Watkins.
The next president needs 270 electoral votes to win.
