I think he needs to do something to stop this momentum that is building against him, it's becoming dangerous for his chances imo. the market is spooked by something today too, trump's drifted more to 2.66, with biden at 1.75. I think on paper a lot of this should hurt the democrats, but atm it just doesn't seem to be the case, or at least not as much as it is hurting trump. this new shooting for instance should be worse for dems ( just going of the headline, I haven't read about it yet tbh) but since they distanced themselves from the defund the police narrative and it's happened on trump's watch these things just don't seem to be benefiting trump. I think it's possible that 2nd wave fears and biden's possible debate gaffe's will not hurt as much as they should.
and this is before things that will hurt trump straight out like a possible stock market crash like you said. a small concern i have for trump too is that he's firing on all cylinders atm, he's got a shit ton on his plate and he's going balls to the wall between dealing with covid, trying to get the economy going, foreign relations with china and the rest of the world, campaign rallies, twitter, smack talking with dems etc etc. while biden is just at home taking it easy letting trump wear himself out.
yeah don't get me wrong harris winning would be crazy but I have almost no risk as I have been trading her price from 1000/1 to 150/1 currently, so it's basically a free bet at this stage, If she gets VP she should shorten below 100/1 maybe to like 50/1 or something where i can lay her a bit for soem extra profit on everyone else while still having a giant green on her, that's the plan anyway.
