Unclear if this is discrete or indiscrete.

"Different sectors have different point spreads, reflecting their importance in the Victorian-era electorate."

Spread itself has discrete values, though maybe be representing something indiscrete.

"In this era, most British subjects didn’t have the right to vote, so the point spreads aren’t simply based on population distribution. They’re based on the number of voters..."

The indiscrete game world concept of unknown changing actual population, but a number of voters would be discrete.

"...and each sector’s overall impact on the election results, factoring in the value of campaign contributions, endorsements, and other means of influence."

Contributions value may be discrete, but endorsements and other means of influence I'm not sure about.

"As the game progresses, parties will reach maximum or minimum values in some sectors. These maximums and minimums affect the game’s strategy and evoke real-life political effects. No matter how strongly Scotland prefers one party over another, Scotland’s impact is limited by the number of voters in Scotland."

So, there are indiscrete things in game world represented, but it has a number of voters and that number itself would be discrete.

"The Conservative Party can also earn popularity points in the Workers sector, but can’t earn any red points there because Workers who support the Conservative Party prefer moderate MPs."

Seems like a calculable, discrete representation of the indiscrete.

Functionally it appears as a digital computer from the outside of the game, because of the point values.

But the point is that the game represents calculations happening in that game world with indiscrete variables like "variable support from unknown population", hence the "analog computer inside..." in the title.
