"Ben Carson Vaults to Lead in Latest Journal/NBC Poll."

"The result marks the first time since June that the Journal/NBC News poll has found a Republican other than Mr. Trump to be leading the GOP field. Some 29% of GOP primary voters rank Mr. Carson as their top choice, while 23% favor Mr. Trump. Florida Sen. Marco Rubio and Texas Sen. Ted Cruz rank third and fourth as the top pick of 11% and 10% of Republican primary voters, respectively. Some 8% prefer former Florida Gov. Jeb Bush. No other Republican garners more than 3% support."

The WSJ reports. Since the poll was both before and after last week's debate, we can't really tell what the effect of the debate was. But what surprises me — looking at the charts at the link — is that Marco Rubio declined a percentage point. And Bush stayed in the same place.
