As you already know, Blanco won in Louisiana, 52-48%. This Times-Picayune claims that on the one hand Jindal got almost twice the number of black votes Republicans normally get, on the other hand, "Blanco’s remarkable victory Saturday was propelled by her ability to capture more white voters than Democrats typically can count on in statewide races against Republicans." Ron Brownstein thinks this: "Like a retreating army pushed back to the sea, Democrats rallied to hold the Louisiana governorship Saturday when Lt. Gov. Kathleen Babineaux Blanco defeated Republican Bobby Jindal.
The win will probably avert a full-scale panic among Southern Democrats unnerved when the GOP captured governorships in Kentucky and Mississippi two weeks ago.
Yet the overall trend in the region since President Bush took office still looks ominous for Democrats."
