If the left has to trump up Trump's badness so egregiously, it makes it seem like it's crying wolf. He's already bad enough that nobody should have to exaggerate it.
I think the Democrat voters concerns are largely driven by a genuine fear of repeating Germany’s historical mistake of not confronting authoritarian threats early on, rather than simply aiming to smear Trump. And it’s not as though Trump hasn’t given them reasons for alarm. For example the Russia investigation, which he labeled a 'witch hunt,' was triggered by suspicious behavior on his part. As I’ve mentioned before, when he had a meeting with Putin that typically requires security detail and official records but chose to meet privately without oversight, I expected people to be suspicious. . While the investigation didn’t conclude that Trump colluded with Russia, it did uncover actions that landed figures like Paul Manafort, Michael Flynn, and Roger Stone in serious trouble. I personally don’t see alarmist rhetoric as problematic, so long as it doesn’t dehumanize a group of people and remains focused on the parties actually involved.
Democrats criticize Trump specifically = Good
Trump labels all Democrats as bad = Bad
Republicans criticize Kamala specifically = Good
Kamala labeling all Republicans as bad = Bad (though I haven’t seen this)
It's different.
