If Hillary Clinton were to run for president in 2016 and win her party’s nomination, a majority of registered voters nationally would support Clinton, regardless of her Republican opponent. Her closest competitor is Paul Ryan who Clinton leads by single digits. Clinton has a similar lead when up against former Republican presidential nominee Mitt Romney.
