Donald Trump's Primary Results

Donald J. Trump has underperformed in the first three primary contests compared to pre-election polling. Three theories are suggested as possible explanations: undecided voters supporting Nikki Haley, incorrect electorate makeup in polls, and a potential Hidden Anti-Trump vote. Pollsters may have missed Democratic-leaning voters turning out to support Haley. The turnout problem may persist in competitive primaries. The Hidden Anti-Trump vote theory suggests anti-Trump voters may not be as likely to respond to surveys, potentially affecting general election polling.
