A recent NBC News poll shows Donald Trump and Kamala Harris tied at 48% support, three weeks before Election Day. The results reflect a sharp tightening of the race, with Harris' summertime momentum fading and Trump benefiting from Republicans rallying around him after earlier polling struggles. The poll highlights voters' strong focus on abortion as a top issue and a large gender gap, with women backing Harris by 14 points and men supporting Trump by 16 points. Both candidates face challenges, with 10% of voters undecided and third-party votes adding uncertainty to the outcome.
