Your astonishing stupidity never ceases to amaze me. It is evidently clear you have NO idea whatsoever what an anecdote is.
An anecdotal evidence is a personal testimony; in other words a story. This is contrasted with empirical evidence, where you accumulate information using DATA, which requires sample sizes, like polls. Empirical evidence is infinitely more reliable than anecdotal evidence, for obvious reasons. Polls are empirical evidence. They use sample sizes, often times with sample sizes over 1000. And most of them show Biden with a gigantic lead. You can choose to ignore that in favor of anecdotal evidence, but it only shows your colossal stupidity.
And also this part of your response: "It's safe to say the anecdotal evidence doesn't favor Biden." makes absolutely no sense. Anecdotal evidence doesn't favor one side over the other, because it's anecdotal evidence that relies on personal accounts. From my personal experience, most of the houses I see all have Biden signs. Using my anecdotal evidence, Biden is winning. Your anecdotal evidence shows otherwise. But how can Biden and Trump be simultaneously winning? And that is why anecdotal evidence is not reliable.
