This is unfortunately much too simplistic. First, elections are not held daily so nothing could happen until the next election. Second, if in fact 80% of our society could actually agree on something that is a single issue and no votes are ever about a single issue. Third, the voting system itself is flawed, as we saw in the last presidential election when the majority of people did not vote for the "winner".
As
@neroden has pointed out, many of the worst problems in our system are the anti-democratic features/flaws. I was against getting rid of the Electoral College until 2016.
Its original intent was to abstract the presidential election process from the people directly. It was instituted in an era of monarchies where national democracies pretty much didn't exist. While the idea of rule by the people was one of the ideals this country was founded on, the founders also were skeptical that the people could exercise wise judgement so they made the House direct vote of the people and made Senators and the president elected with more distance from the people. A constitutional amendment made senators directly elected and picking the electors by popular vote in each state evolved over time. A few times states became states too late to hold a popular election for electors and the state legislature picked them, but South Carolina had the legislature do it until 1968.
As pretty much all states picked their electors by popular vote, the elector process became sort of a ritual rather than anything with any meaning. Just as in the UK, the Queen can technically veto any bill, but she never does because she is effectively a figurehead. Though in a serious crisis she could act. Emperor Hirohito, who was also pretty much a figure head in Japan stepped into direct political action for the first time in 1945 to end the war when the two factions couldn't come to any kind of decision.
However the elector process was kept and in part because it would take a constitutional amendment to get rid of it, but also because it was said the electors would serve as a backstop to prevent someone clearly unfit who was able to bamboozle enough voters to sneak in. In 2016 it became obvious that while there were a few electors who voted for someone other than the person who won their state, Hillary Clinton lost more electoral votes to unfaithful electors than Trump did (Hillary lost 5 and Trump lost 2, 4 of those for Hillary were in my state).
In the last 20 years the popular vote winner did not win the presidency twice. One election was decided by a questionable SCOTUS ruling and a lot of chicanery in Florida. The other had significant interference from foreign powers.
It's time for the electoral college to go. At this point the people are wiser than the electors.
