IT WAS a “big win” tweeted Donald Trump on April 25th, as he congratulated the Republican winner of a special congressional election in Arizona’s eighth district. And yet, he complained: “Press is so silent”. Neither of these claims was true. The media has been pouring over the outcome of a race, in a staunchly conservative district on the edge of Phoenix, that would normally deliver a boringly predictable Republican win. That is because the Republican victory there was much narrower than usual.
