The Media follows orders of the billionaire factions that own the Media. Disparaging stories about Harris appear in the Media because the owners directed them to be there.
It indicates the billionaires are having second thoughts about their factional choices to appoint Harris as the Democrat candidate.
Perhaps they believe that Harris will be no more capable of following directions than Biden. And it may have occurred to some of the faction members that their factions will be served up for dinner if the pro-Harris factions succeed at putting her into office. Does anyone want taxes on "unrealized capital gains". The upper income one-percenters surely do not want such a thing. It would harm the rest of us as well.
The billionaires have a better chance of remaining unmolested in a Trump administration. President Trump will be too busy dealing with a massively insubordinate Federal and Military bureaucracy to go after the oligarchs.
President Vladimir Putin of Russia uses a much more effective means of dealing with the oligarchs. He has them thrown from an upper story window. The Democrats can only wish they had that much power. President Trump will be restrained by laws and the most he can do is oversee the replacement of senior government officials.
Trump can still fire the military “bureaucracy”.
