The Georgia runoff shows that Democrats have figured out a winning strategy | Andrew Gawthorpe

Taken as a whole, the midterms have provided a ringing endorsement of the approach to politics favored by President Joe Biden. From the first moment it looked like he would enter the 2020 Democratic primary, Biden was maligned and mocked for suggesting that the path to a Democratic victory lay through gains with independent and suburban voters. Critics argued that the country was so deeply polarized that swing voters no longer existed, and that appeals for bipartisanship would fall on deaf ears. In their view, the only viable strategy was to mobilize the Democratic base with leftwing appeals, even at the cost of losing voters in the center.

Nor should the hidden strengths of the president himself be dismissed. Biden has long been dismissed by people who imagine themselves to be more politically sophisticated. Over the past few years, he has left their predictions in the dust again and again. Most crucially of all, he is the only Democrat who has beaten Trump in a one-on-one contest, the sort which allows him to highlight the contrast between Bidenism and the radicalized opposition most convincingly.
