Trump must tread carefully because the MSM developed an immune response after Reagan.
They did a post-mortem and blamed themselves for not taking Reagan out and creating a two-decade interruption in the “transformation of America”. They’ve taken steps to ensure that never happens again.
Exhibit A is the absolute, literal early destruction of Sarah Palin.
Here's the difference: Sarah didn't have the GOP establishment or really any money to defend and attack.
Trump doesn't have the gop establishment, but he has tons of money and all it can buy.
Sarah wasn't used to the viciousness of the press. Trump has lived with it for decades and learned how to use it for his benefit.
