Unfortunately the way I see it is Biden will lose for two reasons:
Regardless of policies or how terrible the alternative is. I dont think most people are going to think much past "Things are expensive now, and oh great a super old white dude".
Man I would love to see this, but its one of those things that I will believe when I see. I hope I have to eat my words on that too. Even if so, I dont think decriminalization would mean much to people in terms of getting out to vote. Most people who are really passionate about this over other issues have had the states handle it for them already. Dems waited too long for Federal Decriminalization to be a big motivator in a national election in my opinion.
Different types of people. Its a shame Democrats have such an uphill battle to rally around candidates because those voters hold their leaders accountable, almost to a fault. The republican voter base is made of people who are basically in a cult, or are one issue voters.
