If Mitt Romney was an NFL football player, chances are he'd sign with the Miami Dolphins.

That's because the highest-earning ZIP code for Romney's campaign is the 33480 of Palm Beach, Fla. — a direct result of a Jan. 12 fundraiser that Dolphins owner Stephen Ross hosted for Romney.

"The event, which local press described as possibly setting ‘a record as the largest political fundraiser ever held in the state,’ raised an estimated $1.8 million — not all of it from 33480 — from the 750 donors who attended," Zachary Abramson wrote Monday for Politico.

(Aside: football fans will surely find irony in the fact that Ross succeeded in helping Romney raise so much cash, because Ross has recently encountered zero success trying to persuade NFL stars to take his money. As Mike Florio detailed Monday for Pro Football Talk, over the last 18 months the Dolphins owner has pushed hard to lure prized personnel to his team by offering tens of millions of dollars in guaranteed money to coaches Jim Harbaugh and Jeff Fisher, and free agent quarterbacks Peyton Manning and Matt Flynn — only to repeatedly see his top targets use Ross's offers as leverage for procuring a comparable payday from another team.)

OpenSecrets.org listed Romney's top 10 fundraising ZIP codes. Aside from Palm Beach and Greenwich, Conn., the other eight slots in Romney's Top 10 are all occupied by Manhattan ZIP codes.

Citing data from the Federal Election Commission, Politico's Abramson compared figures from the 2008 and 2012 election cycles and discovered a significant decline in Romney's campaign contributions from Utah donors.

"Four years ago, ZIP 84604 — Provo, home to Brigham Young University — topped Romney’s money list. And 84108, a Salt Lake City suburb, also cracked Romney’s Top 10. … Romney, through January, raised just under $2.6 million from Utah ZIPs that begin with 84 — that’s down from more than $6 million in 2008. Provo’s 84604 ZIP saw the largest decline: $300,000."
