The obvious is that they are fishing for votes. Warren has a putative weakness with African American voters. Tom Steyer is unknown to them (as he is to a lot of people). Harris is sinking fast and needs to shore up her rep and Julián Castro’s campaign has barely been registering enough to keep him on the debate stage.
But beneath this are more disturbing beliefs, one of which is on the edge of disgusting and actually racist: that African Americans prefer to be lied to than told the truth. The corollary to this is that they are easily lied to if you stir them up. The level of disrespect in this is off the charts.
This dishonesty to black people practiced by Warren and the others — fomenting anger toward the police — makes the lives of African Americans worse, frequently endangering them and resulting in their deaths, as Heather Mac Donald details so well in her The War on Cops. I often wonder how many liberals have read this book. I imagine very few because it so undermines their virtue-signaling narrative with uncomfortable and overwhelming facts. For someone like Warren to fan the flames of cop-hatred is despicable and immoral, but not surprising for someone so willing to lie about her Indian ethnicity. If black lives truly did matter to her, she would never say such a thing.
