The online version of From the Politics Desk, an evening newsletter by NBC News, covers the unfolding events of Kevin McCarthy's revenge tour, shedding light on his primary targets and the motivations behind his support for challengers of Republicans who opposed him. Rep. Nancy Mace finds herself at the center of this power struggle, grappling with the consequences of her historic vote to oust McCarthy as House speaker.

During an interview at her campaign headquarters in Daniel Island, S.C., Mace emphasized the importance of honesty, integrity, and trust in her political fight against primary challengers backed by McCarthy. The escalating tensions within the Republican Party are underscored by McCarthy's actions, with operatives aligned with him funneling significant financial resources into these primary races as a test of his influence.

As the political landscape intensifies, the newsletter also delves into the polling dynamics between Joe Biden and Donald Trump, revealing contrasting public perceptions of the candidates' characteristics. The national CBS News/YouGov poll showcases divergent views on toughness and compassion, indicating potential vulnerabilities and strengths for each candidate in the upcoming elections.

Moreover, the newsletter highlights the nuanced preferences of swing voters, posing a pivotal question on whether toughness or compassion is more crucial in determining the electorate's choice for the presidency. These insights underscore the complex interplay of character traits and policy stances that could sway voter decisions come November.
