If you can't even be bothered to look up the platform of the person running against Trump, it really does show how insincere you are, but as others might want to read it I'll post it anyway -
End of Mandatory minimums
End, once and for all, the federal crack and powder cocaine disparity
Decriminalize the use of cannabis and automatically expunge all prior cannabis use convictions
End all incarceration for drug use alone and instead divert individuals to drug courts and treatment.
Eliminate the death penalty
Use the president’s clemency power to secure the release of individuals facing unduly long sentences for certain non-violent and drug crimes.
End cash bail + Stop jailing people for being too poor to pay fines and fees
End the federal government’s use of private prisons, building off an Obama-Biden Administration’s policy rescinded by the Trump Administration. And, he will make clear that the federal government should not use private facilities for any detention, including detention of undocumented immigrants.
Now you might well say he won't actually do that, politicians never fulfil all their manifesto promises, but my answer would be he's sure as hell more likely to do it than the president who's advocating the opposite of every one of those policies and has done nothing but move social and justice reform backwards over the last 3 1/2 years.
