"Nikki Haley Gains Momentum with Koch Endorsement and Grassroots Support"

Influential billionaire Charles Koch has endorsed Nikki Haley for the Republican presidential nomination, choosing her over frontrunner Donald Trump and Ron DeSantis. The endorsement comes as Republicans seek a tested leader to pull the nation back from the brink and move away from Trumpist extremism. Internal polling shows Haley in a strong position to defeat Trump in the primaries and outperform him against Joe Biden in key battleground states. The Koch network's endorsement is seen as a significant boost for Haley's campaign, although critics argue that she is not a conservative moderate.
