Every dictatorship is a little different. Some don’t hold elections, some do. Russia is one of those that does, but the outcome is never in doubt.
Russia actually has a sophisticated “democracy theater.” There are loyal “opposition parties” (like the Communist Party, and the “Liberal Democratic Party” which is nothing of the sort) that get all kinds of perks from the ruling party (United Russia). And then you have the genuine opposition (Navalny, etc.) which is routinely arrested and disqualified.
In terms of daily life, Russia is on the whole a bit freer than the completely totalitarian North Korea. But both Russia’s and North Korea’s (officially the “Democratic People’s Republic of Korea”) claims to being “democracies” can be easily dismissed.
Now...
“Majority rules” is what every other true democracy on earth practices. And it is what we ourselves practice in elections for Senator, Governor, the House of Representatives, and lower offices.
The GOP does just fine.
All a popular vote for President (or its equivalent) would do in practical terms is make the GOP have to move slightly to the left to remain competitive, and make all of us less beholden to the particular whims of those who live in swing states.
Presidential Elections would actually be contested in our largest population centers (NYC, LA, SF, Chicago, Dallas, Houston) rather than completely written off because of the solid red/blue states they’re in — wouldn’t that be something?
