What county would need to be removed to flip a state to the other presidential candidate.

I'll start Clark county. Remove this county and the state of Nevada will be solid Republican.

Illinois: Cook County
Pennsylvania: Philadelphia County
Virginia: Fairfax County

This is pretty much true for all Democratic-leaning urban states. I really don't think its possible to do this with any republican state.

If this counts: remove El Paso, CO and it's forever a Likely D state.

Remove Maricopa, AZ and it's a Tilt R swing state.

[The world will shine with light in our nightmare]

Oh yeah, and remove St. Louis City (or St. Louis County) and Democrats say bye-bye to Missouri for a generation (unless Todd Akin runs again).

It's not true that removing a single county from all urban Democratic states will flip the state.

Removing Miami-DADE county, Florida would flip Florida to likely republican.

Hennepin County, Minnesota

Removing Miami-DADE county, Florida would flip Florida to likely republican.

Broward County even more so than Dade

Removing Multnomah, OR would make Oregon a swing state (2012 would have had a 1% margin for Obama, 2004 would have had about a 6% margin for Bush). The only reason it wouldn't completely flip it is because much of the Portland metro area spills over into Clackamas and Washington Counties.

Removing King, WA would similarly make Washington a swing state (about a 3% margin for Obama in 2012, about a 4% margin for Bush in 2004).

IL: Cook
WI: Dane or Milwaukee
AZ: Maricopa?

[Spark]

Allegheny county, PA

[Holmes]

Clark, NV

[Wiz in Wis]

IL: Cook
WI: Dane or Milwaukee
AZ: Maricopa?

Alternatively, remove Waukesha and Wisconsin is the new Illinois.

[Drew]

OH: Cuyahoga?
VA: Fairfax?

Virginia: Fairfax County

Well, Obama won Virginia by ~149,000 in 2012. He also won Fairfax County by ~109,000, so the state would still be in the Dem column if you removed the county. Although if you threw in Arlington County and the City of Alexandria then the state would have flipped.

In 2004 in Iowa it was Sioux county. This is probably one of the very few Republican examples.

Remove Maricopa, AZ and it's a Tilt R swing state.

In the same vein, removing Waukesha County would make it much harder for Republicans to ever win Wisconsin, at least at the presidential level.

New York becomes a battleground without four of the five boroughs in NYC (Queens, Brooklyn, Manhattan, Bronx).

Maricopa county in AZ is more GOP than the state as a whole. If you remove that, AZ becomes lean R to swing state.

Remove Denver county, Adams, Jefferson, Arapahoe and Broomfield, CO becomes a lean R state.

Remove Cook county from Illinois, it becomes a moderate R state.

Remove Clark county from Nevada, it becomes a moderate R state.

New York becomes a battleground without four of the five boroughs in NYC (Queens, Brooklyn, Manhattan, Bronx).

Except you're getting rid of 4 counties there, not to mention 45% of the state's population.

You would need to remove Nassau and Westchester as well for good measure.

Very few Democratic states would solidly flip if you took away just their biggest county, most would need several counties removed or would turn into swing states. Illinois and Nevada are the only states I could think of off the top of my head where taking away their largest counties would unquestionably swing the states firmly into the red column, with perhaps Pennsylvania also following similar suit.

If Kentucky is very close, it would be either Boone County or Jefferson County, depending on which party wins the state.

[MASHED POTATOES. VOTE!]

No one mentioned the obvious?

The obvious is New Castle County, Delaware.

[Ebsy]

Missouri 2008, there are many counties that McCain won by over 4000 votes that without, Obama would have won.
