A new poll indicates the race in the Texas Republican primary for U.S. Senate could be headed for a runoff.
The survey by the Texas Tribune and the Texas Politics Project at the University of Texas at Austin found Lt. Gov. David Dewhurst with 40 percent support. He was followed by former Texas Solicitor General Ted Cruz at 31 percent.
Former Dallas Mayor Tom Leppert pulled 17 percent, and former ESPN football analyst Craig James stayed in low single digits at 4 percent.
A majority vote is required to get the nomination.
At a small private fundraiser in Frisco Monday morning, Cruz said the poll results show GOP voters are aligning with his campaign and the race is heading to a runoff.
But via Twitter, the Dewhurst campaign questioned the poll's findings and its methodology.
Setting the tone for the last five days of early voting leading to the May 29 primary, Dewhurst unveiled a new TV ad featuring Gov. Rick Perry, who says, "David Dewhurst repeatedly cut spending. David strongly opposes a state income tax."
The commercial is obviously responding to Cruz's claim that Dewhurst has promoted a state income tax.
Dewhurst has tapped his considerable personal fortune to outspend Cruz in TV ads statewide.
Dewhurst is also due in the Dallas area Monday for "get out the vote" events.
