John Cassidy has a good article at The New Yorker site praising Biden's "big tent" strategy. He talks about three big challenges Biden is surmounting:
1. Uniting the Democratic Party after a chaotic primary season.
2. Fashioning a coherent response to the tumultuous events of 2020
3. Avoiding giving Trump an easy target
On #3, he breaks it down this way, with the help of some fellow named Teixeira:
"The third challenge that Biden faced was to avoid giving Trump an easy target. The pandemic has made the dodging part easier. Hunkered down in Wilmington, Biden largely has left the President to dig his own hole—which he has done, ably. But Biden has also reached out to Trump Country. The first of his Build Back Better speeches was delivered in Rust Belt Pennsylvania: it included calls to restore American manufacturing and “buy American.” As well as adopting some of the language of economic nationalism, Biden has rejected certain progressive proposals, such as defunding the police and enforcing a complete ban on fracking, that might alienate moderate whites in battleground states.
This is smart politics, Ruy Teixeira, a polling expert and senior fellow at the Center for American Progress, told me. Despite the changing demographics of the United States, whites who don’t have a college degree still make up about forty-four per cent of the eligible electorate, according to Teixeira; in some places, such as parts of the Midwest, the figure is even higher. “You cannot cede massive sections of the electorate if you want to be successful politically,” Teixeira said.
In 2016, Trump carried the white non-college demographic by thirty-one percentage points at the national level, according to Teixeira’s analysis of exit polls and election returns. Biden has narrowed the gap to twelve points, Teixeira said, citing a recent survey. That is similar to the margin in 2008, when Barack Obama defeated John McCain and the Democrats increased their majorities in both houses of Congress. As it is often defined, the Obama coalition consisted of minority voters, college-educated white liberals, and young people. Teixeira pointed out that Obama’s ability to restrict McCain’s margin in the white non-college demographic was also important, and if Biden matched that feat in November, he said, it could be of enormous consequence. “This is not the only thing that is going wrong for Trump,” Teixeira said, “but it is the thing that could give the Democrats the big victory that they need to govern effectively.”
None of this means that Biden is a lock for the Oval Office. Between now and November 3rd, something could conceivably shift the momentum against him, such as a Vice-Presidential pick that backfires, a major slipup in the debates, or a surprising economic upturn. Right now, though, the challenger’s strategy of keeping the focus on the incumbent and pitching a broad tent that accommodates anyone who wants to see the back of Trump is working well."
Data note: despite my best efforts, they managed to garble my description of the data sources. The 2016 data are from the States of Change project and have nothing to do with the exit polls; we modeled data from the Cooperative Congressional Election Survey, the Census' American Community Survey and election returns down to the county level. The 2020 data are from the Democracy Fund + UCLA Nationscape weekly surveys and are based on surveys from May 1 onward, a total of 43,000 cases.
That said, still a great article!
