The Democrats are understandably shoveling anything and everything at the barn door. The propaganda memes emerge in a steady stream from the various ops rooms.
Some are a bit weak like the "urine based case" thing referring to Trump's demand that both he and Biden be drug tested before the 1st debate, but the latest shovel full contains the accusation that after his business lawyers did their magic Trump paid very little income tax for a number of years. For a lot of people this is a serious charge. It is not for me.
The truth is that anyone with any sense pays as little income tax as the law allows. If your tax lawyers and accountants can produce losses in a present year or previous years as carry overs then you apply them to your taxes. To do otherwise is simpleminded.
