I researched this exact question. There is a way called deep canvasing https://www.vice.com/en/article/how-to-change-a-voters-mind-is-deep-canvassing/
It’s scientifically proven. Try having a one on one conversation with someone. Listen to what they say and respond with empathy. Then gradually and calmly introduce your message that is related to what they said. For example if the person you are talking to said they are worried about grocery prices and specifically egg prices you could mention that bird flu was the root cause of the price increase and that Trump’s tariffs will raise prices on groceries. Building trust helps your message get across. I’ve had personal conversations with Trump supporters who trust me and you’d be surprised how much success you can have.
And this will lower my grocery prices how?
