After reading through the article linked, I do not believe this article makes the same claim as this post. The article claims that the election will be tough for Biden and that he and Trump have a 50/50 chance at being elected. This is reflected in this ABC News report, which finds roughly even public trust between either candidate. ABC News has been found reliable by Ad Fontes Media.
Additionally, the claim posed is speculative and, thus, cannot be true or false. There is no telling what will happen, so that can only be hypothetical at the moment. What is true is that polls are finding more trust for Trump than for Biden. What this statistic will lead to cannot be predicted at this moment.
