Considering you're calling the democratic party fascist on twitter (and a sitting republican congressman said Biden put out the hit), I think knowing his motivation is somewhat important.
My prediction is that he's an online schizo with mixed politics and nobody is going to be able to map him on Democrat/Republican lines. Everybody will feel worse about everybody else and more polarized.
Electorally, good for Trump because there's no way the Dems have the guts to run an aggressive campaign after this. They're already pulling ads. Everybody is falling in line behind Biden because they don't want to shake anything up right now. They might just roll over.
