The road to the White House is certain to run through Wisconsin this fall, but one county in the Badger state could be the ultimate battleground.
In fact a new book suggests the county that surrounds Green Bay is one of seven counties across the country that could determine the next president.
Every four years Wisconsin is seen as swing state or battleground state, even though Barack Obama, Bill Clinton, and every other Democratic presidential candidate has carried the state in November for the past three decades.
During that same time period, Republican Governors Scott Walker and Tommy Thompson have had success at the state level.
"If you want to win Wisconsin you have to win Brown County big," says political blogger and talk show host Ed Morrissey.
He has looked at the numbers out of Brown County in his book, Going Red which serves as a road map for presidential candidates, specifically Republicans.
Mitt Romney barely beat Obama in Brown County with Paul Ryan on the ticket. But Morrissey says Republicans failed to crush it, they needed a double digit win.
"The were not able to make emotional connections to the voters," said Morrissey, "because they didn't take the time find out who the voters are and what is it that moves them emotionally in elections."
Morrissey points out President Obama was able to tailor his message. So what about 2016 with Bernie Sanders against Hillary Clinton?
Ted Cruz won Wisconsin, but Donald Trump remains the current frontrunner nationally.
The other key counties across the country are in Florida, Ohio, North Carolina, Virginia, Colorado and New Hampshire.
