Nothing has been settled and it's all to play for, as I explain in a new piece on the American Compass blog:
"While Joe Biden will be the 46th President of the United States and Donald Trump will join the small club of incumbents who could not get re-elected, it’s fair to say that Biden’s triumph was not so overwhelming that it even begins to settle the question of which party will dominate the 2020s.
Biden will likely end up with a roughly 4 or 5 point popular victory, but his electoral vote advantage (306-232) simply replicates Trump’s advantage in 2016 and similarly includes several states taken by only the narrowest of margins. The GOP actually made gains in the House of Representatives and state legislatures. And the Senate likely remains out of reach for the Democrats.
These mixed results reflect both strengths and weaknesses in each party’s coalition. The Biden coalition continued to dominate the rising demographic constituencies at the heart of the party’s support base but underperformed with some of these voters relative to 2016. The Trump coalition retained strong support from its key white noncollege constituency but still saw significant defections of these voters to the other side, particularly in the suburbs, where there was also a surge toward Biden among white college voters. Neither party is in a secure position; both need to expand their support bases by winning back voters they have lost and retaining new voters whose aspirations may differ from their core constituencies. Here are the daunting challenges each party coalition faces.
The Biden coalition may be summarized this way. Looking across available survey data, he carried nonwhite voters by a wide margin (though less than Clinton’s in 2016), ran up a modest advantage with white college voters and reduced Clinton’s 2016 disadvantage among white noncollege voters (particularly in suburban areas where most of these voters actually live). He carried young voters by a solid margin, as did Clinton in 2016, and made substantial improvements among senior voters, nearly breaking even with them.....
[T]he election results suggest some huge challenges for the Biden coalition going forward. Latinos are driving the growth of the nonwhite population in the country and, while still strongly Democratic as a whole in this election (63-35), that figure still represents a serious decline of Democratic support from 2016, particularly in Florida and Texas, but also in states like Arizona and Nevada.
Shoring up support among these voters is key to the future of the Biden coalition. The coalition also needs to retain the support it gained among both white college and noncollege voters and then make additional gains to insulate the coalition from populist backlash.
This will entail a Biden administration that cleaves closely to its implicit philosophy of progressive centrism and resists pressure to pursue unpopular causes. Above all, the administration must succeed in what it is surely its central task—containing the coronavirus and rebuilding the economy—by any means necessary. If that means priorities of the activist left must be deferred to accomplish this central task, Biden cannot hesitate to deliver the bad news.
As the early years of the Obama administration demonstrated, if voters do not see the main task as successfully accomplished, the potential for electoral backlash and coalitional fragmentation is vast.....
Which coalition is in the better position for a future majority? At the moment, the Biden coalition corresponds closely to the emerging Democratic majority coalition as originally envisioned — it includes not just strong support among growing demographic constituencies but also an improved share of white noncollege voters as well as more senior voters. That could be a winning formula to build on for the rest of the 2020’s.
But as we know, demography is not destiny. The Trump coalition showed surprising strength in this election and chipped away at some constituencies the Democrats are counting on for future strength. More of the same could undermine the Democrats’ potential winning formula and possibly fuel a Republican resurgence as the decade unfolds."
