Again, that too depends on where the remaining votes are coming from. He is the favourite, yes, but both Dane County and Milwaukee County - home to the two major cities - have quite a significant amount to report in yet and both are strongly Democratic (currently 75 and 60 percent Biden, which is expected to be a tad higher in the mail ballots). It's not just numbers, it's also where they are coming from.
Like in Michigan, Trump is the favourite, but Biden definitely still has a realistic chance. I mean, if he doesn't, the current betting odds of around 1.7 for Trump must be absolutely free money for anyone who is convinced Trump can't lost it anymore.
