The poll, conducted by Public Policy Polling, a Democratic firm from North Carolina, found that Democrat Alison Lundergan Grimes leads McConnell 45 percent to 44 percent in the 2014 race for the U.S. Senate.
The poll, a telephone sampling of 1,210 Kentucky voters, has a margin of error of plus or minus 2.8 percentage points means the race is essentially a dead heat.
The poll was commissioned by the Progressive Change Campaign Committee and Democracy For America, two organizations that oppose McConnell. The survey was conducted between July 19 and July 21.
The poll also found that 51 percent of voters oppose McConnell’s job performance while 40 percent said they favor his performance.
The New York Times polling blog, fivethirtyeight.com, ranked PPP as the 15th most accurate public pollster in the 2012 presidential election. Despite being a Democratic pollster, the blog found that PPP overestimated Republican nominee Mitt Romney’s performance by 1.6 percentage points.
