Here are excerpts from a selection of some of the most popular opinion pieces of 2018.
To say that Donald Trump is not acting presidential is not to romanticize what we have seen from previous inhabitants of the office. But it is to hold him accountable for going far beyond the proper limits on presidential behavior.
The biggest danger is that by tolerating Trump's behavior in office, the public will make what he is doing and saying part of our conception of what it means to be presidential.
It is vital that members of both parties admit what they see when these moments happen and avoid normalizing these kinds of reckless departures from presidential history. For if the political class, and the public, starts to brush these moments off as "Trump being Trump" or "nothing worse than what we have seen" we will lower the bar so far it will be impossible to ever repair the presidency.
Lucia Brawley: Let's be honest about Aziz Ansari
As a society, we must take this incident -- appearing in the public consciousness during our #MeToo moment -- as an opportunity to have some painful, nuanced conversations.
For example: Sexual assault and rape are never the victim's fault. But we cannot indiscriminately start destroying careers over consensual sexual activity, which based on her account is what this case appears to be.
When we do that, we trivialize the brave victims who are coming forward about actual sex crimes.
Simone Biles: I went from foster care to the Olympics
Although I was young when my foster care ordeal began, I remember how it felt to be passed off and overlooked. Like nobody knew me or wanted to know me. Like my talents didn't count, and my voice didn't matter.
Finding a family made me feel like I mattered. Finding a passion, something I loved and was really good at, made me feel like I mattered. Representing my country and being part of such an amazing Olympic team matters, as does being a role model for those looking to fulfill their own dreams.
Cameron Kasky, Parkland student: My generation won't stand for this
We can't ignore the issues of gun control that this tragedy raises. And so, I'm asking -- no, demanding -- we take action now.
Why? Because at the end of the day, the students at my school felt one shared experience -- our politicians abandoned us by failing to keep guns out of schools.
But this time, my classmates and I are going to hold them to account. This time we are going to pressure them to take action. This time we are going to force them to spend more energy protecting human lives than unborn fetuses.
Peggy Drexler: Why does Melania stay?
But perhaps most important, although divorcing Trump would surely please the "Free Melania" crowd, the first lady hasn't really shown that she cares much what other people think of her -- or needs to be saved.
She has not tried particularly hard to win public approval: Besides her scant appearances and botched RNC address, she's become known for wearing the wrong things at the wrong time, like when she donned a pair of Manolos to visit victims of Hurricane Harvey. Which is also why it's perhaps too hopeful to expect that the pressure of these new revelations (which, let's be honest, are likely not new to her) will cause her to leave the life she seems comfortable in -- one that's very clearly sponsored by, if not warmly inclusive of, the President.
Gloria Borger: The great unraveling: Trump's allies are really worried about him
Not since Richard Nixon started talking to the portraits on the walls of the West Wing has a president seemed so alone against the world.
One source -- who is a presidential ally -- is worried, really worried. ...
Even by Trumpian standards, the chaos and the unraveling at 1600 Pennsylvania Avenue are a stunning -- and recurring -- problem.
But there's an up-against-the-wall quality to the past couple of weeks that is striking, and the crescendo is loud, clear, unhealthy, even dangerous.
