The narrative in this latest revelation isn't just that he hasn't been paying anything in federal taxes. It's also that the "great" business man lost almost one billion dollars in one year, using bankruptcy laws to stiff small businesses and causing people to lose their jobs, and then paid nothing in federal taxes for years and years. He can't fall back on the "because I'm smart" response when the whole thing rests on his being a total, abject failure at business.
This should have legs through the VP debate on Tuesday, and that's good.. Unfortunately, it seems there is another leak from you-know-who supposedly coming on Wednesday, which will probably be "Squirrel!" for the MSM after that.
