So far, front runner Mitt Romney has spent $124 million in the primaries and has received 4.1 million votes, for a cost of $30/vote. Gingrich spent $39 million or almost $18/vote. Santorum was the most efficient spending just $27 million, or a bit less than $10/vote. Next up is the general election. Assuming the winner will need 65 million votes, at just $10/vote that means raising $650 million! Democracy ain’t free.
