US presidential election remains too close to call as polls show tight race

As the U.S. presidential election approaches, polls show a tight race between Kamala Harris and Donald Trump. A recent poll indicated Harris has a slight lead in Iowa, but conflicting data from the Trump campaign raises questions about poll reliability. Polling has historically struggled with accuracy due to high non-response rates and the unpredictable nature of voter turnout. While past elections saw significant polling errors, averages have generally reflected public sentiment accurately, though they cannot predict outcomes. In 2024, slight shifts in polling could lead to different electoral outcomes for either candidate. Pollsters have adjusted their methods since previous elections, but uncertainty remains until votes are counted.
