What's a vote cost? A delegate vote goes for $45,000 to $4 million.

If you take the presidential candidates and divide money spent by delegates won, here's what you get:

• Mike Huckabee ... $45,000
• John McCain ... 57,000
• Hillary Clinton ... 89,000
• Barack Obama ... 121,000
• Mitt Romney ... 654,000
• Ron Paul ... 4 million

Rudolf Giuliani spent $48 million and didn't win a single delegate. You do the math.
