All of a sudden, Tucker Carlson has roared back to the forefront of Republican politics. Once the top-rated anchor on Fox News — only to be abruptly ousted 15 months ago, his national platform yanked out from under his feet — Mr. Carlson has made an improbable re-emergence into America’s living rooms at this week’s Republican National Convention. He is even returning to prime time: Mr. Carlson is set to deliver a televised address to the convention on Thursday in a coveted slot shortly before Mr. Trump accepts his party’s nomination. Mr. Carlson once electrified Fox viewers with racial grievances and flimflam conspiracy theories. But behind the scenes over the past year, Mr. Carlson has become more deeply allied with Mr. Trump than at any point in his long relationship with the former president, a man for whom the broadcaster once expressed deep ambivalence.
