I meant that that local stochastic things affecting individual voters are not important in the year-to-year variation in election outcomes, compared to systematic effects like the economy.
If you had an exact fraction of voters who would break for which candidate (which polling isn’t accurate enough to give), you still would face uncertainty about turnout.

The standard error of polling is usually pretty small.
