Representative Democracy yeah. The people voted in Trump who now gets to appoint those positions.
Well no. The people voted in Clinton, and the Electoral College upweighted some votes and downweighted others in a way that favors Trump. The EC once had a distinct purpose, but right now just seems to give Republicans a structural advantage, to the ultimate detriment of Democrats and Democrat-leaners in small or rural states.
I agree that it is not healthy that ~10-12 states have higher importance in the presidential election, but it would be rather similar in a straight popular election.
An intermediate step would be to increase the size of the House of Representatives.
