The polling data has shown all year that Trump was trailing Biden. Why do you find it so implausible when the election as indicated that exact same fact? Even Fox News put him behind for most of the year. His behavior has lost him the support of a lot of different groups, including anyone who is afraid of dying of Coronavirus, black lives matter, women, old people, and other groups that you need in order to win the election. And yet, based on nothing except Donald Trump's word, you believe that the only way he can lose is through fraud. You are simply out of touch with reality if that's what you think.
