Eagles fans crept up the western spine of New Jersey, but Giants and Jets fans dominated the north.

The Giants and Eagles dominated New Jersey's football fandom, according to NJ.com readers, although one wonders if the results for Big Blue would come up differently today.

More than 21,000 people voted in our town-by-town NFL fan map, battling it out for fan supremacy in each of New Jersey's 565 municipalities using our live-updating fan map.

It would be easy to expect the Eagles to come out as the geographical victor (they did), having no competition for the southern half of the state, but the team's fans also voted in overwhelming numbers. The 11,000+ votes for the Eagles topped all other votes combined over a four-day period.

What was interesting about how fans voted in this map was that it wasn't so much a north-south Jersey battle as it was an east-west Jersey battle. Eagles support ran deep up the western half of the state, pushing as far north as Hunterdon and Warren counties, but not east of there.

Giants and Jets support, meanwhile, pushed south along the Jersey shore into parts of Ocean County.

Though it didn't draw a straight line, the voting pattern gives credence to the historical boundaries of East and West Jersey formed in Colonial America in the 1700s. The dividing line between Jets/Giants and Eagles fans loosely followed the Keith Line, an arrow straight line that most notably forms the northeastern border of Burlington County.

Up north, the Giants took most of the territory, though not by much in most cases, and a smattering of green can be seen in just about every county north of Trenton. Jets support was strongest in Union and Middlesex Counties, while the Giants had multiple strongholds in the northeastern quarter of the state

After the Jets' clear victory Sunday and the Giants' embarrassing last-minute loss to the Dallas Cowboys in the opening week of the season Sunday, however, one wonders how different the map may have looked this week.

But the Eagles dominance can be seen fairly clearly in the county-by-county totals.

Teams other than the Jets, Giants and Eagles took in no more than a few percentage points overall in most places. In Somerset County, however, an even split between the Cowboys, Baltimore Ravens, New England Patriots and 'Other' categories was good for more than 11 percent of the combined vote, the highest of any county.
