Why did the makers of the constitution place filters?

The French revolution convinced many that mass voting could not take place as the common man was not educated enough to vote.

So in the Constitution, the States Legislatures chose the senators, and the electoral college elected the President.

It was also believed that too much direct majority rule could possibly hinder the rights of the minority groups, that is why filters were placed.

it refers to race, i am pretty sure this was a popular term in nazi germany or something.

depending on what kind of map for example a pltical maps works in many ways this iss how it works it shows the areas and places the democratics and the repbulcicans reside for example if   texas chooses trump for president there a republican state and if   califronia chooses hillary there a democratic state.
