We didn't learn back in 2000 either. I'm not hopeful 2020 will be much different. 2024, maybe, when Millennials are expected to become the majority voting block, but for 2020 the Democrats are too busy doing exactly what needs to be done for them to loose 2018 midterms and the 2020 election.
Really, they need to themselves get foaming at the mouth pissed off, much like the Republicans did with the Tea Party and with Trump. Democrats and Liberals don't need to cry and whine, they need to yell and roar. The party itself must carefully plan the next four years to turn this into a monumental win, but they are too eager to just accept defeat and not look into how a catastrophe can be opportunity.
9/11 was a very confusing time. Bush Jr. Has record popularity through te early part of his administration, and many has not yet seen the true coats of our intervention in Afghanistan and Iraq. The constant drumbeat of war and Al-Qaeda's threat was a challenge, and too many politicians who should have known better bowed under the political pressure. . . The American people wanted war.
In 2004, instead of fighting this policy, we chose John Kerry because he was a Vietnam vet, another incorrect centrist choice who was not inspiring. Plus, his war record was smeared, and Fox News finally became a real force. Murdoch stopped screwing around and finally became the propaganda arm of the Republican Party. . . as it still is today.
We didn't know how to deal with all of this then, like we struggle today to deal with foreign hacking and fake news (as was demonstrated by me earlier in this very thread).
But yes, you're right. This is an opportunity, but we have to be honest and cool-headed. Admitting that we lost the election is not admiring defeat at all.
The battle goes on, as long as many decent people as possible stay engaged. Some of those decent people are conservatives, and some are liberals.
Luckily, more are actually liberals, which is an advantage that we can't forget. It's something the DNC forgot too, because the real majority in this country was only pandered to in this election. The next candidate needs to energize and most of all. . . be a true liberal.
If we learn that lesson, we'll never lose again.
