New Democratic Louisiana Senate Poll Finds A Tied Race, But With Strong Likelihood of Republican Gains

A recent television ad paid for by by 'Friends of Mary Landrieu' shows citizens of a rural Louisiana town watching Landrieu TV appearances in which she takes it to the Obama Administration on a number of issues. Separating herself from an unpopular president is a must if she hopes to hang on to her seat.

Of the premier 2014 midterm contests, the Louisiana Senate race is *the* most likely to flip into Republican hands, at least according to current Huffington Post Pollster averages. That's why the  new Public Policy Polling survey allowed the Landrieu campaign to breathe at least a slight sigh of relief, especially considering the recent spate of run-off polling. An incumbent who is tied with their opponent at 47% wouldn't typically be received as welcome news for most political campaigns, unless six of the eight polls taken this year found that opponent ahead.

But as far as Democrats are concerned, the good news stops there. Because a closer inspection of the PPP memo and crosstabs suggests little room for improvement for the incumbent:

The likely Landrieu/Cassidy match up for the December runoff is tied at 47. Among those who support Maness or Hollis or are undecided for the November election, 68% move to Cassidy for December compared to only 11% who move toward Landrieu. Even though only 6% of voters are undecided in that match up, they don't set up great for Landrieu- 61% voted for Romney to 20% who voted for Obama, and she has a 14/65 approval rating.

It's July, and if you buy the PPP numbers, a mere 6% of likely voters are undecided. So no matter where they end up, the Louisiana Senate race is bound to be at least remotely close.

As Nate Silver has argued before, at least at the presidential level, there comes a point in the election cycle where job approval ratings become a leading indicator of final result. So let's divvy up that tiny 6% slice of the electorate to the Louisiana Senate candidates, with 14% going to Mary Landrieu (her approval rating among undecided voters), and 65% going to Republican Bill Cassidy (her disapproval rating among undecideds).

Suddenly, the GOP challenger jumps out to a 51-48% lead, which goes to show that despite undecided voters being few and far between, Landrieu is unpopular enough with them to make a difference. The same thing happens when you reallocate undecideds according to how they voted in the 2012 election (61% for Romney, 20% for Obama). What was a 47-47 tie again becomes a 51-48% Cassidy lead.

Buoyed By 2008-like Racial & Partisan I.D. Survey Findings, Sen. Mary Landrieu's Still Locked In A Tight Battle

Cassidy and Landrieu are locked in a tight battle, though it's Phil Robertson who appears to be the strongest candidate to take on the Democratic incumbent, at least according to PPP. His lead grows to nearly double digits if PPP had found racial and partisan identification along the same lines as 2010, and not 2008.

Three-term Louisiana Senator Mary Landrieu (D) is no stranger to tough races. In 1995, before being elected to the Senate, she finished third in her state's jungle primary for the governorship, shutting her out of the eventual run-off election. The next year, her attempt to leap into federal office nearly failed, when she defeated former Democrat-turned-Republican Woody Jenkins for the U.S. Senate seat by an exceedingly narrow 50.2 - 49.8% margin (under controversial circumstances), making it the most competitive of thirty-three Senate races held nation-wide that day.

For reelection in 2002, she narrowly escaped defeat by a 51.7 - 48.3% margin, even as Republicans, bolstered by intense focus on foreign policy in the wake of the September 11th attacks, racked up wins across the country. Only three Senate races were more competitive that cycle.

Barack Obama's election in 2008 brought with it a Democratic wave that saw their numbers swell in the Senate by eight, and by 21 in the House. Needless to say, it was Landrieu's best performance for her seat to date. She won by a reasonably decisive, though far from overwhelming 52.1 - 45.7%, making it the sixth most competitive Senate battle of the cycle.

Unfortunately for Senator Landrieu, it doesn't appear as if this cycle will be any different from the last three. And most of the polling to date has indicated it could be her toughest yet. Furthermore, the chart below, compiled from Huffington Post Pollster and RCP, indicates things may be trending Cassidy's way:

But what's more? Three of the five pollsters to dive into the field in Louisiana have found an interesting trend. At least in terms of racial/ethnic and partisan identification, PPP, Rasmussen, and Harper are finding an electorate more akin to the 2008 presidential election, when Landrieu won by her most impressive margin to date, than in 2010, when David Vitter (R) easily dispensed of his Democratic opponent by 20 points.

Unfortunately, there were no exit polls in Louisiana in 2012. But in 2008, as the historical candidacy of Barack Obama brought out a particularly racially diverse electorate nationwide, nearly 1/3 (29%) of Louisiana's electorate identified as African American, virtually identical to recent PPP (28%), Rasmussen (29%), and Harper Polling (29%) findings. White voters made up 65% of the 2008 electorate, again, nearly the same as found by PPP (66%), Rasmussen (66%), and Harper Polling (64%).
