In more troubling news for vulnerable Sen. Mary Landrieu (D-LA), she and Republican challenger Rep. Bill Cassidy (R-LA) are tied in a heated Senate runoff with each sharing 47 percent of the vote in a new poll by a democrat-leaning polling firm.

There is six percent of voters who say they are undecided when it comes to a runoff between Landrieu and Cassidy, but those votes are not going to be easy for Landrieu to lock down.

“Our last couple of Louisiana polls have found the candidates within a point of each other,” said Dean Debnam, president of Public Policy Polling. “The big question is whether Mary Landrieu has much room to grow if she doesn’t get to 50 percent in November.”

As for the November primary race, the Public Policy Polling firm has Landrieu at 44 percent and Cassidy with 27 percent. Col. Rob Maness takes 8 percent, while long-shot State Rep. Paul Hollis (R-Mandeville) takes 5 percent.

And more bad news for Landrieu, more Louisianans disapprove of her performance in Washington than approve. 42 percent of voters polled said they approve of the job Landrieu has done while 52 percent of voters say they disapprove.

Cassidy, though, does not poll the best when voters are asked how they view him. Just 28 percent of voters said they viewed him favorably. Meanwhile, 36 percent view him unfavorably.

Landrieu is not being helped by President Barack Obama during her re-election, being that he has a disapproval rating of 56 percent.

In another race, the Governor’s election, Sen. David Vitter (R-LA) is leading all potential candidates. Most importantly, Vitter leads New Orleans Mayor Mitch Landrieu with 48 percent to 44 percent.

PPI conducted the poll of 664 registered voters between June 26-June 29. The PPI poll has a margin of error of +/- 3.8 percent.
