I don’t know very many people but I did my part by convincing family and friends to vote for Trump.
If every Trump supporter is just doing this, it will make a major difference.
Of course, I couldn’t convert everyone.
Some people are so far gone they can’t be reached.
Changing to them is admitting they were wrong and they can’t do that. They are hardened in their hearts and stiff necked.
If you convince one person there's a good chance they will convince another. It backs up their decision and commitment.
