It effectively is, in a lot of areas.

First: lol no. It isnt the same as wanting trump to win, but ill grant that it does effectively hurt his chances ?in the case he remains unmoving.*

Second: protest of Biden is only damaging to his campaign if you think Biden only has to not be Trump, and isn't capable of hurting his own chances by doing something exceedingly dumb, like publicly funding a genocide.

Those of us protesting him now are doing him a favor by giving him a chance to address the issues that would otherwise tank him.
