About 40% of the America seems to still support Donald Trump, under most polls. It certainly isn't true that 40% of the media supports Donald Trump. As an external viewer, it's easy to imagine no-one was ever going to vote for Donald Trump, no-one ever supported him, and no-one supports him today, but that's clearly not reality.
Personally, I'd never have voted for him, but it's hard to understand why many of those who voted for him continue to support him, and it doesn't feel like the media is doing a good job here.
