JOY! IRRATIONAL EXUBERANCE SOARS TO NEW LEVEL. The polls suggest that many Democratic voters feel better about the new and untested candidacy of Kamala Harris than they did about the old and enfeebled candidacy of Joe Biden. But the polls cannot measure the off-the-scale enthusiasm for Harris and new running mate Tim Walz that is appearing every day in some of the nation’s biggest media outlets.

Sometimes videos are more effective than lists. Look at this compilation of media figures marveling at what a “happy warrior” they believe Walz to be. He’s America’s coach or he’s America’s dad or both. And he’s not at all weird, like some other people. “Everybody likes Tim Walz,” says one talking head. “Hope, optimism, joy,” says MSNBC’s Joe Scarborough, characterizing Walz. (You might remember that not all that long ago, Scarborough was assuring us that Biden was super sharp and on top of things as president.)
