He's against crap now. Which crap is bigger? There wasn't 24/7 anti-Trump rhetoric being played either. Much harder to win this election than 2016.
When I say "crap," I mean his opponent. In 2016, it was easier for voters to say, "well, there's a lot I don't like about Trump, but Hillary Clinton is the worst." The reason why is that Republicans had been building the case against her since Trump was still married to Ivana. That isn't true of Biden. We've really only been ripping on him for a few years, and he doesn't give as much ammo. He gaffes a lot, but he doesn't put off the slimy condescension that Hillary put off.
You are correct that the media is tougher now, but they were horrible in 2016 too - much worse than they were with previous GOP nominees.
However, we disagree on two issues. First, you seem to think that because the media sucks, messaging basically doesn't matter, because they'll crap on him anyway.
I reach the opposite conclusion. Because the media will crap on him, that's all the more reason to have solid messaging - not because it'll force the media to be fair, but because you have chances to speak directly to the people and because what you say can either undermine or reinforce the media narratives.
For example, let's look at the recession/Covid angle since you mentioned that.
I think most voters understand that the recession is a product of Covid. I don't think they blame Trump for Covid, but they do blame him for how we've handled Covid. The media has told them that we are chaotic and don't take it seriously. Of course, that isn't reality. In terms of what has actually been done, the federal response has been pretty organized within the constitutional framework, and they've taken it seriously. But actions aren't driving the narrative unless someone is driving home the actions with articulately-stated words. So when Trump publicly clashes with his own people on the issue, that reinforces the media narrative of chaos. When he ridicules mask wearing, that reinforces the narrative that he doesn't take it seriously. What if instead of doing that, he stayed on message with what the federal government is actually doing? What if he didn't make fun of mask-wearing? It would be harder for the media's narratives to succeed.
Second, we disagree on another matter, which is that Trump has an easier time now in some respects than he had in 2016. For starters, he has a generally good record. He had no record in 2016. In addition, though Biden isn't as offensive as HRC was, his Party is MUCH, MUCH worse and is easier to target. They're talking about ruining the federal courts, throwing out the US Senate, and they condone violence. They are a disaster, and that's a huge weapon he could be deploying now that he couldn't deploy then.
My point is that this race is winnable (and certainly was very winnable) even with a Covid-induced recession, and the media doesn't decide everything. Candidates, campaigns, and messaging still matter a lot. Mike Pence showed how it can be done.
