I feel like by now those people you describe should have realized Trump is doing no good on those issues they supposedly cared about. And if they had even a tiny modicum of empathy, they should be scared shitless about the people getting disappeared.
The economy is shit, eggs are more expensive than ever but those same people that insisted those issues alone should decide the fate of the country don't seem to care anymore. Why?
People who voted for Trump weren't stupid, they've been molded into it by the most expensive proaganda apparatus that ever existed. Ask yourself, why isn't Trump's popularity declining in the face of such incompetency?
Now, what can a nice talk achieve that material reality failed to convince those people of?
