I think people were just trying to save themselves from a Trump presidency and it was a valiant effort. Just because something might not work is no reason not to attempt it, especially when the stakes are so high. Unfortunately, it was too little too late. The Democrats need to do some serious introspection now.
Almost three million more voters cast their ballots for Hillary Clinton than for Donald Trump, allowing her to win the popular vote. However, the electoral votes went in Trump's favor. Because of the disparity between the votes, Clinton supporters made an effort to sway the electoral college voters to change their ballots in her favor. It didn't work, but it was worth the effort because the campaign to do so put Trump on notice that the majority of the people in the United States are not happy with him being in the White House.
Trying to sway the electoral college was not worth it in the end, because ultimately it didn't have an impact. The people in electoral college were bullied. They were harassed day and night by people who were upset that Clinton lost the election. This only sent a message to Trump supporters that Clinton supporteres are sore losers.
Trying to sway the Electoral College away from Trump was not worth it in the end. In fact, Clinton lost more faithless electors than Trump did. Trump lost 2 electoral votes, while Clinton lost 5. Therefore, the media obsession with Trump losing electoral support was actually misplaced, because the focus should have been on Clinton losing electors.
