I think Republicans need to get out in front and do something cool, like legalize weed and pass legislation forgiving all weed related crimes. They'll get millions of votes.
Also, propose forgiveness for all home mortgage loans. Use the slick buzzwords -- "Why should decent Americans, disproportionately people of color, who are in need be saddled with crippling debt, just to keep a roof over their heads and protect their children?" -- they'll get tens of millions of votes. Every goddam liberal on this thread would vote for D. Trump if he promised that in 2024.
