Retired neurosurgeon Ben Carson now leads Donald Trump in the crucial early caucus state of Iowa.
That’s what a new Quinnipiac University poll shows, at least. It puts Mr. Carson ahead of Mr. Trump by 28 to 20 percent among likely Republican caucus participants. That’s a near-reversal of their positions from September, when the real estate mogul/reality star led Carson, 27 to 21.
The only other GOP hopefuls to crack double digits in the new Quinnipiac numbers were Florida Sen. Marco Rubio, at 13 percent, and Texas Sen. Ted Cruz with 10 percent.
