Everyone hates the Electoral College whenever their candidate wins the popular vote but loses the contest. There are always calls to abolish it. But the Founders did it on purpose. They feared the “tyranny of the majority” and wanted a layer of reliable, somewhat educated, logical men to have the ability to negate the popular vote if some lunatic convinced the People to vote for them. And it may have worked that way in those days, when people were not career politicians and wanted only to do their jobs as statesmen and get back to their lives.
But now the parties are so polarized that there is no chance they would go against the party nominee. Both parties select party shills and yes-men to be the electors.
So don’t expect anything different this time from other times when the candidate has lost the popular vote but won the electoral votes.
