WASHINGTON (Reuters) - Following Republican President-elect Donald Trump's resounding victory in this month's election, some U.S. pollsters are scrambling to understand why their surveys once again underestimated his support among American voters.
Polls before the Nov. 5 vote had shown Trump trailing Democratic Vice President Kamala Harris by 1 percentage point, according to an average of dozens of national opinion polls compiled by 538, a website on data analysis for politics and sports. With vote tallies nearly finalized, Trump led Harris nationally by 2 percentage points: 50% to 48%.
