If Bernie Sanders won only one county outside of Vermont...

[Mr. Illini]

...which one would it be? Assume that all contests are held on the same day (to avoid questions of momentum and potential drop outs).

I'd say it would be Tompkins, NY.

Followed by Albany, NY, Mendocino, CA, Humboldt, CA, Dane, WI, Boulder, CO.

I also think he will win a number of college-dominated counties such as Johnson, IA, Lane, OR, Douglas, KS, Champaign, IL, Johnson, IL, Monroe, IN, Washtenaw, MI.

[Famous Mortimer]

Hennepin, MN

[Crumpets]

Grafton County, NH, Franklin County, MA, Boulder County, CO or San Juan County, WA in that order. He'd probably have a really good shot at Humboldt County, CA, if it wasn't so late in the season.

[VPH]

Missoula, MT; San Miguel, CO; Boulder, CO; Athens, OH; Jefferson, IA; Berkshire, MA; Grafton, NH; Cumberland, ME; Lane, OR; Tompkins, NY; Dane, WI; Cook, MN; Knox, ME; Waldo, ME

[ElectionsGuy]

One of the liberal college town counties. Grafton, NH. Dane, WI. Washtenaw, MI. Athens, OH. Tompkins, NY. Monroe, IN. Boulder, CO. Montgomery, MD. Johnson, IA etc.

[Mr. Morden]

Strong chance of it being somewhere in Minnesota or Washington, since those are caucus states.

But I'm guessing you want us to assume that every state holds a primary instead?

Grafton, NH or Johnson, IA.

Centre County is in play as well for the Sanders campaign

[Famous Mortimer]

Hennepin, MN

People on Atlas have a warped view of the MPLS area

Why do you say that? They have a Black Muslim representative who is actually probably slightly to the left of Bernie. The local primary voters/convention delegates have a long history of picking candidates to the left of whoever the party establishment has picked (Rybak, Hodges, Franken, Dayton).

[Famous Mortimer]

Also, I would say he's almost a lock to win Jefferson, IA, ie the country where the Maharishi University of Management is. Dean won it in 2004 and Kucinich came in second. Paul also won it 2 times.

[Kingpoleon]

Grafton, New Hampshire, where Dean built up a progressive base, or Jefferson County in Iowa. Likely an early state, that is.

Black Muslims do not vote for Jewish socialists

[Famous Mortimer]

Most people in Minneapolis are not Black Muslims. Most of them are White. They just voted for one and that shows how liberal they are.

Are you (and the people who emptyquoted you) implying that most residents of Minneapolis are black Muslims, and that all black Muslims are anti-Semitic?

[Figueira]

Anyway, aside from what's already been mentioned, there's Hampshire County, MA.
