The Trump campaign has torched almost a billion dollars to run 8-9 points, on average, behind Biden. When the candidate is self sabotaging the campaign the money doesn't matter.
It seems a lot of the campaign money is being used on spending to enrich himself and his cronies. He’s literally fleecing his supports to line the pockets of himself and other. Honestly I feel the Trump campaign is one big money laundering operation at this point.
