A WELCOME piece of news arrived for Donald Trump on the first day of the Republican National Convention. The criminal case against him for allegedly removing classified documents from the White House (and piling them in, among other places, a ballroom and bathroom at Mar-a-Lago, his Florida home) was thrown out by the presiding judge. Higher courts will probably look askance at the ruling, but it means that Mr Trump’s tactics have pushed his trial past the November election—if it ever begins at all.
