Considering this candidate will pretty much spend the whole time bashing trump how does this not hurt Biden?
This is the beauty of third party candidates—they get coverage on the mass media which Trump supporters do not believe or trust.
The only people who trust or believe the mass media are Biden supporters or potential Biden supporters.
That means that the attacks on President Trump just lure folks who would not vote for President Trump into voting for the third party instead of Biden.
This is perfect stuff—and that is why the sharp Democratic political operatives are freaked about third parties of any kind.
