In nationwide polls, Donald Trump has defied multiple legal snarls to pad his already healthy margin over potential challenger Ron DeSantis for the Republican nomination. So far, those two swamp all other possible names, such as Nikki Haley.

As for state polling, South Carolina numbers last week from Winthrop University have Trump at 41% and DeSantis 20%, while the two locals got only 18% (Haley), and 7% (Tim Scott). Likewise in New Hampshire with its first primary, where a St. Anselm College poll in late March reported Trump 42%, DeSantis 29%, popular Governor Chris Sununu a mere 14% and Haley 4%.

Reporters on the politics, religion, and religion-and-politics beats should especially keep a hawkeye (so to speak) on Iowa, with its crucial first-in-the-nation caucus next January — turf already well-trod by GOP hopefuls. An April 4 poll of likely G.O.P. caucus-goers by J.L. Partners shows Trump 41%, DeSantis 26%, and Haley a 5% also-ran.
