Associated Press: “Biden, too, regularly discussed his potential pick with his sprawling network of friends and advisers. He used Obama in particular as a sounding board, though confidants to both men say the former president was careful not to tip his hand in those conversations as to whom he preferred. But in private, Obama suggested to others that he believed Harris was the favorite.”

Rep. Ilhan Omar (D-MN) beat back a well-funded primary challenger on Tuesday in Minneapolis, virtually guaranteeing a second term in Congress, Axios reports.

Conspiracy theorists won a major victory on Tuesday as Marjorie Taylor Greene (R), a supporter of the convoluted pro-Trump movement QAnon, triumphed in her House primary runoff election in Georgia, all but ensuring that she will represent a deep-red district in Congress, the New York Times reports.

More than a dozen candidates who have expressed some degree of support for QAnon are running for Congress as Republicans, their path cleared by President Trump’s own espousal of conspiracy theories.

Washington Post: “The elevation of Greene to federal office would mark a watershed for adherents of QAnon.”

Walter Shapiro: “Many volumes will be written about why Biden chose Harris. But the truest bond between them may be the simplest—they are both politicians in the best sense of the word. They understand elections, Capitol Hill, and how to be tough without losing your sense of humor.”

Washington Post: “The Trump rally may be a thing of the past. At the least, the signature stew of tribal politics, showmanship, insults, outrage, humor and hero worship that propelled Donald Trump’s improbable victory four years ago and that has punctuated his presidency with the trappings of a perpetual campaign, is on a break.”

“Trump appeared to declare the end of the rally era Tuesday. He said the events — the success of which he has always measured by the size of the crowd and the ‘ratings’ — are a casualty of the coronavirus pandemic. Or more exactly, of the dispiriting optics that proper social distancing would mandate.”

Said Trump: “You can’t have empty seats.”

Politico notes Sarah Palin offered some warmhearted and uncharacteristically nonpartisan advice for Kamala Harris as she joined Palin in the small club of women chosen for vice president: “Trust no one new” and “Don’t get muzzled.”

NBC News: “Harris was difficult to pin down ideologically in the Democratic presidential primary, which left many voters wondering what she stood for and hurt her candidacy and ultimately forced an early exit last December before the first votes were cast.”

“But it also now makes her a more complicated target of attacks by Trump, who has also struggled to land a punch on Biden: During the Democratic primary, Harris was a rare candidate who polled near the front of the pack but never earned a derisive nickname from the president.”

Also relevant to an earlier story about Cawthorn deleting photos from Hitler’s retreat: His real estate firm uses the acronym SPQR and he has two Betsy Ross flags displayed in his house — both have been associated with white nationalists.
