Things have got to be bad for Democrats right now as they desperately try to whip up the vote to save the job of California’s Gov. Gavin Newsom in the Sept. 14 recall election. They called in Joe Biden, president of the United States, who is set to make an appearance for their man this week. They called in Kamala Harris, vice president of the United States, longtime Newsom pal, and former California senator, who showed up for appearances Wednesday. Normally, when you’ve got the president of the United States campaigning for you, it’s a wrap. The big guy makes an appearance and the voters come running. Big Guys don’t often do this, and that makes this all the more special. But something doesn’t seem to be happening, so now they’ve pulled out their real ace in the hole, Barack Obama, man of pizazz and charisma, former popular president, since turned Hollywood figure, to try to turn this situation around for embattled Newsom with his familiar pious soaring rhetoric about sweep-of-history, a choice of moving forward or backward. […] The fact Obama has replaced sitting President Joe Biden as the Democrats’ trump factor tells us a lot about how bad things are going.
