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.
