Even if it is way too early, Trump seems a real DOA against Biden (and to some extend Sanders), but all other races seems winnable (EV). There is 15% undesided and a reasonable (IMHO) assumptions that they will break more towards Trump when election is near enough.
Also, if Biden keep these numbers, it will help him greatly during the primaries.
Biden still has room to fall, and that's what will end up making the election competitive if it happens. There's no way that Trump only gets 38% of the vote. His real floor is probably 45%. However, if Biden is above 50% and ahead of Trump by at least 3 or 4% consistently in national polls, he should be favored to win, even if it is narrow. It's still too early to say though.
