Iowa Gov. Kim Reynolds endorses DeSantis

Driving the news: "I believe [Trump] can't win," Reynolds told NBC News in a joint interview with DeSantis, adding, "and I believe that Ron can."

• "And that's a big reason I got behind him," Reynolds said.
• "Not only do we need to make sure that we elect someone who can win and beat Joe Biden, we need a president who has the skill and the resolve to reverse the madness that we see every single day," Reynolds said at a campaign rally for DeSantis Monday.
• "That leader is Ron DeSantis," she added.

Zoom in: DeSantis has bet big on Iowa, saying that he will visit all 99 counties in the state. (So far he has hit 87 counties, NBC News reports).

• A poll out last month showed former UN ambassador Nikki Haley and DeSantis tied in Iowa at 16%.
• Trump had 43% in the NBC News/Des Moines Register/Mediacom poll of likely Iowa caucus goers.

The big picture: Reynolds' endorsement is a change from earlier in the cycle, when she said that she wanted to remain neutral in the Republican primary, a move that is line with previous governors of the first-in-nation caucuses.

• "If I weigh in, I don't know if they'll feel all that welcome," Reynolds told the Des Moines Register in February.

• Trump criticized Reynolds for not endorsing in the crowded primary.

Between the lines: Trump already lashed out at Reynolds over her anticipated endorsement of DeSantis, saying that it will be the "the end of her political career," according to a post on Truth Social.

• The Des Moines Register first reported on Reynolds' plans to endorse DeSantis.
