The Republican National Convention arrives at an extraordinary moment in what, for many, many, many months had been a tepid, torpid, and tedious turnoff of a presidential election, until in quick succession, two seismic events jolted the race: first, Joe Biden’s debate debacle in Atlanta, and then the heinous and horrifying attempt on Donald Trump’s life. Tens of millions of Americans who’d been studiously averting their eyes from the campaign are suddenly watching, rapt. Late on the first night of the G.O.P. convention, I convened a conversation with two former Republican strategists, Stuart Stevens, best known for running Mitt Romney’s 2012 presidential campaign against Barack Obama, and Tim Miller, the king of The Bulwark, to chew over an exceptionally newsy and noisy stretch in our politics.
