Sen. Ted Cruz (R-Texas) is looking more and more like a top-tier contender in Iowa.
The Republican presidential candidate surged to a close No. 2. position in a new Quinnipiac University poll published Tuesday.
Real-estate mogul Donald Trump held onto his first-place status, with 25% support among likely Iowa caucus-goers.
But Cruz was close behind with 23% -- within the poll's margin of error.

"Last month, we said it was Dr. Ben Carson's turn in the spotlight. Today, the spotlight turns to Sen. Ted Cruz of Texas," Quinnipiac pollster Peter Brown said in a statement.
Brown added, "The Iowa Republican Caucus has become a two-tiered contest: Businessman Donald Trump and neurosurgeon Ben Carson lead on the outsider track, and Sens. Ted Cruz and Marco Rubio lead among party insiders."
Cruz also surged in a CBS News poll of Iowa published Sunday. In that survey, Trump led with 30%, followed by Cruz with 21% and Carson with 19%.
