It's the same story over and over. All the swing states are very close. If the polls are right, then it's going to be a close election. If they are not right and they are all wrong in the same directon (which makes sense), then it could be a big electoral victory for either candidate. My head tells me that Harris would be the one being underestimated (Biden won in 20, insurrection, Roe vs Wade, better campaign by Harris) but I am not very confident about that.
