"Trump and Haley Lead Republican Field in New Hampshire After Iowa Caucuses"

Former President Donald Trump solidified his position as the front-runner for the Republican nomination after a decisive win in Iowa, leaving his rivals facing long odds. Criticism of Trump has not gained traction, as seen with the exits of anti-Trump candidates Chris Christie and Asa Hutchinson. Trump's lead among Republican voters has only expanded, and the primary process may conclude sooner than expected due to rule changes favoring Trump. Former Trump U.N. ambassador Nikki Haley faces a crucial test in New Hampshire, where she has gained ground but still trails Trump in the polls.
