The public gives other prominent presidential candidates either a lukewarm or an unfavorable reception, including Marco Rubio (+5), Jeb Bush (-2), Hillary Clinton (-6) and Donald Trump (-22). These results are based on Gallup Daily tracking from Oct. 19-Nov. 1, a period that spanned the third Republican debate.

But as might be expected for a first-time presidential candidate with a limited national profile prior to mounting a campaign, Carson is not as well-known as other candidates. Carson’s overall “familiarity” score — the total percentage of Americans with a favorable or unfavorable view of him — is 63%, well behind Clinton (92%), Trump (90%) and Bush (76%).
