Carson surges past Trump in Iowa poll

Politico reports:

Ben Carson has surged past Donald Trump in Iowa, according to a Quinnipiac University poll of likely Republican caucus participants out Thursday.

The retired neurosurgeon leads the Republican field with 28 percent, while Trump has fallen behind with 20 percent. A September survey had Trump at 27 percent, and Carson at 21 percent.

Also scoring a boost — Florida Sen. Marco Rubio, who comes in third with 13 percent, after attracting only 5 percent support in last month's poll. Following Rubio in the most recent survey is Texas Sen. Ted Cruz with 10 percent, Kentucky Sen. Rand Paul with 6 percent, and Carly Fiorina and former Florida Gov. Jeb Bush, both with 5 percent. All other candidates are under 3 percent.

The non-establishment candidates continue to shine.
