Head-to-head, former Florida governor John E. "Jeb" Bush barely beats his acolyte Sen. Marco A. Rubio in the Feb. 24-25 Howie Carr/Gravis poll
of 513 registered Republican voters, but in an open field Bush is in a virtual tie with Wisconsin Gov. Scott K. Walker with Rubio finishing third...
"Pitted against each other, Bush is at 40 percent and Rubio is at 36 percent," said Doug Kaplan, the managing partner of Gravis Insights, the Florida-based firm that conducted the poll. The poll carries a margin of error of 5 percent. The total may not round to 100% because of rounding.
But, when the field is opened up to other candidates, the dynamic changes, he said. "We are seeing the early stages of two-man horse race between Bush and Walker."
In the open field, Bush still leads with 23 percent to Walker's 22 percent, he said.
"But, Bush v. Walker is, again, inside the margin of error," he said.
"Rubio is popular, but in his home state, he is taking a back seat to Bush v. Walker," he said. "Even among Hispanics, Bush takes 24 percent, Walker 23 and Rubio, a Cuban-American, comes in third with 11 percent--roughly, his same level of support across the state's Republicans in an open field."
By law, Rubio cannot run for both president and for reelection to the Senate, but, he does not have to make that decision until May 2016and by then, the primary season will be winding down anyway.
The other GOP hopefuls offered in the survey fared like this:
