Washington Post publisher Katharine Weymouth hinted last month that her paper, which is considering putting its downtown home up for sale, might head out of D.C. This could be a ploy to get tax breaks from the D.C. government, but if it’s not, where should the Post move?

As a fictional Deep Throat once urged a fictional Bob Woodward, follow the money. Using the paper’s 2012 circulation figures, let’s find out which future Post jurisdiction would put the paper’s headquarters close to the most readers.

4. Prince George’s County – 57,425 daily circulation.

3. The District of Columbia – 81,040 daily circulation.

Of course, staying in Washington will hardly spook the D.C. Council. Moving along…

2. Montgomery County – 109,006 daily circulation.

At about 109,000 readers, the Post claims an impressive 31 percent coverage rate in Montgomery County. But it still can’t beat:

1. Fairfax County –  119,915 daily circulation.

Wild and woolly Fairfax County emerges victorious in the Poststakes. Just watch out for Fairfax Man.
