That is why we live in a republic and not a pure democracy.
Not really. If the elites who are the electors really voted their conscience, Trump wouldn't be the potus elect. And small states would still have the same clout v. big states if electoral votes in each state were awarded proportionally by the popular vote.
Do you have proof they did not vote their conscience?
Electors are party officials. they are the insiders.
Electors are not all party insiders or elites. The Republican electors were pretty common people, except for a few. The Democratic electors had Clinton and a few high profile names, however for the most part not insiders or elites. I knew an elector a few years back and she was far from an insider or an elite. She was a coworker with a 8-5 job, two kids a husband who worked a job, were just buying a home a modest home in a modest neighborhood.
More or less they are longtime party members and workers who are rewarded. For example.

The state gop executive committees were not, by and large, places where Trump got love. He ran an insurgent campaign to drain the swamp, after all. But that's not really the issue. Almost all electors will respect the votes of their states, even if they voted for someone else in the primary. (and Trump received a plurality not a maj in the primaries)
But that's not really the issue. The issue is the concept of the EC was 1. to prevent a tyrant or someone who didn't respect the notion of transfer of power based on elections and 2. preserve the numbers advantage of allocating the number of electors partially on each state having two senators despite population size.
There's no danger we Americans will elect someone who is not committed to the republic.
If states just allocated electors based on the pop vote in each state, the protection for less populous states is still there. The EC is an anachronism that doesn't reflect the will of voters as well as it could. And I really have no idea who'd have won had the EC been figured proportionally. It still wouldn't be just a pop vote wins.
