Ed Morrissey writes at HotAir.com about Kamala Harris’ prospects as Democratic Party presidential nominee.

Consider this [Friday] the wrap-up to what likely will be the final day of whatever honeymoon Kamala Harris has. The Obamas literally phoned in an endorsement this morning, which means that unless Democrats dig up the corpse of FDR, the potential sugar highs from endorsements have come to an end. Harris may get brief news-cycle boosts from her Veepstakes pick and at the convention, but this introductory week held the most real potential to change the race from the hole Joe Biden dug.

And according to CNN polling analyst Harry Enten last night, that potential went largely unrealized. And in fact, Trump had a pretty good week – again. …

… “All this talk of Harris coming in and the Harris momentum, perhaps ignores a little bit that Trump has a little bit of momentum of his own. So, look at this, a favorable view of Trump. These are all polls taken at the Republican National Convention. ABC News/Ipsos, 40%. That’s the highest ever favorable rating Trump had in that poll. How about Quinnipiac? Forty-six percent. That’s the highest for this pollster. How about the New York Times, the highest in this particular poll?

“So, the fact is, yes, Harris has come in perhaps with a bit of momentum, but Trump is doing polling the best he ever has in the minds of the American public, at least according to these three pollsters.” …

… First, Biden didn’t really crater all that much from the debate. On June 27, the day of the debate, Biden’s RCP average was 45.1, and it bottomed out on July 3 at 43.6. By the time Biden withdrew, though, he’d recovered most of that lost ground to have an RCP average of 44.8. Trump went from 46.6 on June 27 to 47.9 on July 21, but much of that gain came after the assassination attempt and then the GOP convention. 

Second: Harris only negligibly improves on Biden, even in the honeymoon week.
