Some serious money is being pushed through the 2012 race for the White House, and the incumbent, President Barack Obama, hasn't really started spending that much (and his campaign war chest trumps all other candidates).
This morning, the Associated Press examines how much a Republican primary vote has cost, thus far, in ad spending.
The AP said Mitt Romney has seen more ad spending on his behalf than any of his GOP rivals. Romney's ad spending equates to approximately $12.70 per vote and $90,796 per delegate. Romney has collected 495 delegates so far.
Rick Santorum's ad spending per vote has been approximately $3.01 per vote and $28,955 per delegate. Santorum has won 252 delegates to date.
Newt Gingrich's ad spending has been approximately $4.78 per vote and $76,774 per delegate. His delegate total is currently 131.
Ron Paul, who has collected only 48 delegates so far, has ad spending of $6.33 per vote and $129,275 per delegate, according to the AP.
