The tally of votes provides information on different categories of votes earned by the two nominated powers. This provides information on the strengths and weaknesses of your foes according to world opinion.
The first category shows the total provinces in the homeland of the great power plus those provinces conquered militarily since the game began. Since all provinces in this section automatically vote when their nation is nominated this category provides exact information on the size of the two top powers and on their past military successes.
The second category—colonies—represents the total number of provinces colonized by the nominated great power. Since all provinces in this section automatically vote when their nation is nominated this category provides exact information on the size of the colonial empires of the top great powers and on their past diplomatic successes.
