America Is Undergoing Seismic Changes. Its Politics? Hardly.

The country is recovering from a pandemic and an economic crisis, and its former president is in legal and financial peril. But no political realignment appears to be at hand.

In another age, the events of this season would have been nearly certain to produce a major shift in American politics — or at least a meaningful, discernible one. Over a period of weeks, the coronavirus death rate plunged and the country considerably eased public health restrictions. President Biden announced a bipartisan deal late last month to spend hundreds of billions of dollars rebuilding the country’s worn infrastructure — the most significant aisle-crossing legislative agreement in a generation, if it holds together. The Congressional Budget Office estimated on Thursday that the economy was on track to regain all of the jobs it lost during the pandemic by the middle of 2022. And in a blow to Mr. Biden’s fractious opposition, Donald J. Trump — the dominant figure in Republican politics — faced an embarrassing legal setback just as he was resuming a schedule of campaign-style events. The Manhattan district attorney’s office charged his company, the Trump Organization, and its chief financial officer with “sweeping and audacious” financial crimes.
