The Louisville Courier-Journal has this:
For what may be the first time in U.S. Sen. Mitch McConnell’s long Senate career, a Democrat poll shows him trailing a challenger.
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.
Don’t dismiss the pollsters because they’re a “Democrat” firm. Their track record, particularly over the past year, has been right up there. They aced the 2012 elections. …
… The Democratic automated polling firm Public Policy Polling, which took flak all year long from Republicans complaining about its partisan bias, had a very, very good Election Day. …
A Fordham University report released Wednesday ranked the firm first among 28 organizations for the accuracy of its final, national preelection estimates.
The story in the Senate was much the same for PPP. It correctly picked every winner and, in most cases, slightly understated Democratic support and overstated GOP support.
The uniformity of its final, pre-election surveys — for Obama, nearly up-and-down the line — left PPP highly exposed in the event of a Romney victory.
Now, however, the firm can always point to the 2012 scoreboard when confronted with the invariable criticism directed its way. ...Politico
