Jonathan Bernstein: “It’s something that I see pretty often in reader emails and on Twitter, mostly from Republicans but in some cases from liberal Democrats. There’s no surprise here; the vice presidency makes everyone look bad, and the idea that the first Black and Asian-American woman to hold this office is not up to the job is consistent with certain stereotypes.”

“It’s also preposterous. Yes, once nominated almost anyone can win a general election, and perhaps every once in a while a nomination is just luck — in fact, I’ve argued that Donald Trump’s first nomination was largely a fluke. But Harris managed to work her way up in local and state politics in California, without money or family connections on her side, winning multiple nominations. That’s the mark of a good politician. So, for that matter, is securing the vice-presidential nod.”

Politico: “Top Biden officials note that breakthrough infections among the vaccinated are exceedingly rare, unlikely to be severe, and more likely to occur in crowded indoor settings. They’ve been openly frustrated by what they see as overly alarmed coverage of these cases.”

“Still, officials are increasingly worried about the ability of fully vaccinated individuals infected with Delta to spread it to others. There are also several lingering questions about Delta that the CDC is studying — including whether and how asymptomatic individuals can transmit the virus — raising questions about the risk posed by those choosing not to wear masks.”

“It all amounts to a grim political outlook for Biden. The White House had planned to be focused by now on the economy, jobs and infrastructure. Now, it is forced to confront questions about how schools would operate this fall on top of fear from housing advocates over the expiration of an eviction moratorium on Saturday, which came after the White House was slow to call for a legislative fix and which could, those advocates warn, further hamper the pandemic fight.”
