A new poll suggests Republican Texas Senator Ted Cruz is gaining support among likely Iowa caucus-goers.  Quinnipiac University poll results released Tuesday show Cruz passing retire neurosurgeon Ben Carson to claim second place behind Donald Trump.  The same poll had Cruz with 10-percent support a month ago.  It now gives him 23-percent.  That’s a statistical tie with Trump’s 25-percent showing.

The poll has a margin of error of plus-or-minus 3.4 percentage points.
