Donald Trump and Ted Cruz are pounding down the stretch in Iowa attacking each other on multiple fronts as they grapple for the lead with six days to go before the Republican caucuses, according to a new poll from Quinnipiac University released Tuesday.
Trump has the support of 31 percent of likely caucus-goers, to 29 percent for Sen. Ted Cruz of Texas. No other candidate breaks 7 percent, the poll found. Two percent told interviewers they were undecided, but 39 percent of those who chose a candidate say they may change their minds before the caucuses next Monday.
The picture was much the same in Quinnipiac's last poll Jan. 11.
"One week before the caucuses gather, the question is which candidate has the best field organization," said Peter A. Brown, associate director of the Qunnipiac Polling Institute. "If the events of the last two weeks haven't moved the needle, one wonders what would change it in the next six days."
Cruz has the edge among the most conservative Republicans, the poll finds. Cruz leads Trump: 50 percent to 34 percent among those who identify with the tea party; 39 to 27 percent among white, born-again evangelical Christians; and 49 percent to 29 percent among those who say they are "very conservative."
