Trump Takes Aim at Haley as Primary Enters Final Phase in Iowa

Donald J. Trump’s escalating attacks on Nikki Haley both on the airwaves and at his rallies — criticisms she likened Saturday to “a temper tantrum” — captured the turbulent dynamics in the final week before the first votes of the 2024 Republican presidential primary are cast.

Mr. Trump, Ms. Haley and Ron DeSantis fanned out across Iowa this weekend to make their case before the state’s caucuses on Jan. 15 in a frenetic burst of activity as voters endured an unending barrage of mailers, TV ads and door knockers.

But the late gust of campaigning belies a Republican race that has remained stubbornly static for months despite unfolding under the most extraordinary of circumstances. Mr. Trump remains the party’s prohibitive front-runner, even as he stares down legal jeopardy in the form of 91 felony counts spread across four criminal cases.

For months, the date of the Iowa caucuses has been circled on Republican calendars as the first and one of the best opportunities for those hoping to slow Mr. Trump’s march toward a rematch with President Biden. Iowa Republicans, after all, were some of the few voters in the party to reject Mr. Trump in the 2016 primary.

But the former president’s two top rivals — Ms. Haley, the former United Nations ambassador, and Mr. DeSantis, the Florida governor — continue to thrash each other as much as Mr. Trump, though both are badly trailing him in most polls.

The leading pro-Haley super PAC has spent more than $13 million attacking Mr. DeSantis in Iowa since December, including one recent mailer that features Mr. Trump’s distinctive blond hair photoshopped onto Mr. DeSantis, calling the governor “unoriginal” and “too lame to lead.” A pro-DeSantis super PAC, meanwhile, has funded more than $8 million
