Niall Stanage, The Hill:
In the Bloomberg poll of Iowa Republicans, Carson’s favorability ratings were sky-high: 84 percent viewed him favorably and just 12 percent unfavorably.
His net favorability of 72 percent was well clear of his closest challenger by this measure — Sen. Marco Rubio (R-Fla.), who stood at net 50 percent. Trump scored a relatively anemic net rating of 22 percent favorable. Bush did even worse: just 7 percent favorable.
“You are in living saint territory at those kinds of numbers,” Republican strategist Matt Mackowiak said, referring to Carson’s favorability score. “You don’t see that among political figures.”
The affection in which Carson is held by many conservatives is founded in part on his story of rising from childhood poverty in Detroit to worldwide renown in his profession.
