Playbook editor Mike DeBonis and deputy editor Zack Stanton break down the weekend in politics, including the Republican Jewish Coalition conference in Las Vegas, NV.\xa0\n\u201c2024 Republican rivals put Trump on notice,\u201d by Alex Isenstadt in Las Vegas: \u201cIf former President Donald Trump thought his early 2024 announcement would cow prospective Republican primary rivals into submission, he clearly miscalculated.\n\u201cAt this weekend\u2019s Republican Jewish Coalition conference, a parade of ambitious Republicans hit all the notes that politicians eyeing future campaigns for the White House typically do. Their tones and messages varied \u2014 few called out Trump by name \u2014 but collectively they made clear they are not going to back down to the former president after a third consecutive poor election with him at the helm.\nWhat the contenders sound like: \u201cMike Pompeo, Trump\u2019s hand-picked secretary of State and CIA director, warned that for Republicans to win elections, they can\u2019t simply \u2018go on Fox News or send tweets.\u2019 Former New Jersey Gov. Chris Christie, who ran Trump\u2019s transition, said Republicans were losing because \u2018Donald Trump has put himself before everybody else.\u2019\n\u201cNikki Haley, Trump\u2019s U.N. ambassador who said last year she wouldn\u2019t run if her former boss did, has apparently changed her mind. She used her Saturday evening speech here to say she was looking at running in a \u2018serious way,\u2019 and to call for \u2018a younger generation to lead across the board.\u2019 \u2026\n\u201c\u2018He\u2019s not going to have the financial support he had anymore, he\u2019s not going to have the internal support that he had before,\u2019 said New Hampshire Gov. Chris Sununu, whose state hosts the first-in-the-nation GOP primary. \u2018And so therefore, there\u2019s opportunity there. That political weakness is blood in the water for some folks.\u2019\u201d\nSubscribe to the POLITICO Playbook newsletter\nRaghu Manavalan is the Host and Senior Editor of POLITICO's Playbook Daily Briefing.Jenny Ament is the Executive Producer of POLITICO Audio.
