The problem is money. Rich folks and large corporations don't want to pay taxes. Towards that end they will go to any lengths.
Biden has had no problem with his day job. He is the most effective POTUS since FDR. He does have a problem campaigning, specifically feeding a public nurtured on infopablum a message they can easily digest. Kamala doesn't have the messaging problem, but she is Black and a woman, two strikes against her with the big donors.
That’s what’s happening. Don’t be fooled.
