The Democrats aren't even pretending anymore that Joe Biden and Kamala Harris like each other. Each sees the other as an enemy, although neither can do without the other. Biden needs Harris as his insurance policy against being pushed out under the 25th Amendment. Harris needs Biden because, bad as she is as vice president, if Biden boots her, she's got nothing. On Thursday, at the memorial service for Bob Dole, these two disgraceful, immature prima donnas finally gave up any pretense and let it all hang out.
