Regarding copyright... While I do find the excessively long time it takes for a copyright to expire highly questionable, I find I don't feel that strongly about repealing it. Unlike many of the techies around me.
What I do want to repeal is the provisions against breaking "effective technological protections"! The art I want to enjoy should not limit the software I use to do so! That's anti-competitive.
And it really doesn't do anything for workers' rights.
