(CNN) - Iowa's 2.3 million eligible voters have been bombarded with close to $40 million worth of political ads on television this cycle - more than three times the amount spent there in 2004.
That works out roughly to about $17 per voter, between $150 and $200 per expected caucus-goer, and nearly $500,000 per each of the state's 82 delegates in a contest that - unlike 2004 - is wide open on both sides of the aisle.
But what Iowa might lack in population and size, it makes up for in primary calendar position - especially in this truncated cycle when well over half the states will have held their primary contests on or before February 5.
Early momentum - or lack of it - is more likely to make or break a presidential bid.
