WASHINGTON — With two months to go before the mid-term elections, the Republican and Democratic candidates for Arkansas’s U.S. Senate seat are neck-and-neck in the latest poll released Friday by CNN.

WASHINGTON — With two months to go before the mid-term elections, the Republican and Democratic candidates for Arkansas’s U.S. Senate seat are neck-and-neck in the latest poll released Friday by CNN.


The poll showed Rep. Tom Cotton, R-Dardanelle, holding a 2 point advantage among likely voters over incumbent Sen. Mark Pryor. The 49 to 47 percent advantage, however, falls well within the margin of error of plus or minus 4.5 percentage points.


The closeness of the race did not take either campaign by surprise given the plethora of external and internal polling that has already been conducted in Arkansas.


"We never put too much stock in any single poll. The polls are sometimes up and sometimes down," said David Ray, a spokesman for the Cotton campaign.


"We’ve always said this will be a close race," said Erik Dorey, a spokesman for the Pryor campaign.


The poll was conducted for CNN by ORC International, which interviewed 1,010 adults in Arkansas, including 523 likely voters, by telephone between Aug. 28 and Sept. 2.


The survey found a significant difference in support for Cotton between likely voters and registered voters — falling from 49 percent to 38 percent, respectively. Support for Pryor was the same between the two subgroups at 47 percent.


The poll also found that 24 percent of likely voters and 29 percent of registered voters say they might change their mind before Election Day.


Arkansas voters were also surveyed about their opinion of how President Barack Obama is handling his job. Overall, 60 percent disapprove while 33 percent approve. The outcome was substantially the same among likely voters and registered voters.
