Welcome to the third edition of Roll Call’s feature that highlights the most interesting political ads of the week.  

Here is what cut through the clutter:  

Louisiana Senate: A Re-Election That Is Anything but the ‘Big Easy’ www.youtube.com/watch?v=o57WvwHJMS0  

Ad buyer:  Mary Landrieu for Louisiana
Ad buy:  It is a $200,000 ad buy, per The Los Angeles Times .
The race:  Democratic Sen. Mary L. Landrieu is running in a November jungle primary. Unless she takes 50 percent of the vote, she will head to a December runoff against a to-be-determined Republican rival. The race is rated a Tossup  by the Rothenberg Political Report/Roll Call.  

Landrieu is facing another competitive campaign, but her latest ad offers a glimpse of how she’s won multiple terms. In this spot, Landrieu’s father, former New Orleans Mayor Moon Landrieu, makes the case that the stubbornness of his daughter, the Pelican State’s three-term senior senator, protected Louisiana from great villains of recent years: BP, President Barack Obama and the rest of the Senate. One of the main reasons this ad works is is that the father/daughter needling isn’t simply contrived eye-rolls and sarcasm. Often, family political ads are 30 seconds of strained, faux-squabbling.  

Bonus points for working in the fact that Russian President Vladimir Putin banned Landrieu from traveling to Russia, 2014’s badge of honor for any member of Congress.  

The elder Landrieu does the N’awlins accent far better than Dennis Quaid in “The Big Easy.”  

Pennsylvania’s 13th: Bill Clinton Helps Another Comeback Kid’s Bid www.youtube.com/watch?v=yFV7fJoYrRU  

Ad buyer:  Marjorie Margolies for Congress
Ad buy:  The Margolies campaign declined to show its cards on its ad buy. Philadelphia is an expensive market, and rival candidates have accused Margolies of “dipping into funds in the primary that she designated for the general election,”  according to a Roll Call report .
The race:  Ex-Rep. Marjorie Margolies is running in a crowded Democratic primary to succeed Rep. Allyson Y. Schwartz, who is running for governor. The winner of Tuesday’s primary is all-but-certain to win the general. Margolies started the race as an early favorite, but is an underdog headed into Election Day.  

Margolies is Chelsea Clinton’s mother-in-law, but in this situation, Bill Clinton’s appearance in an ad isn’t just about family ties.  

For Margolies, the Clinton favor bank dates back to 1993, when, as a member of the House, she cast what The New York Times’ R.W. Apple, Jr. described at the time as “The Vote .”  

Clinton’s presidency was floundering, and he was desperate to pass his own budget. Margolies bit the bullet and was the deciding vote in his favor. Republicans ran that single moment against her in 1994, and she lost re-election.  

“Twenty years ago, she saved the economy,” Clinton said in the spot, via an excerpt from his April endorsement speech.  

Clinton proved in the 2012 campaign  he has a long memory  when it comes to political payback, including for allies whose loyalty came in far less dramatic displays.
