Landrieu Leads But Not By Enough to Avoid Runoff

A new Public Policy Polling survey in Louisiana finds Sen. Mary Landrieu (D) leading challenger Bill Cassidy (R) in the jungle primary, 43% to 35%.

However, a head-to-head match in a December runoff shows Cassidy leading 48% to 47%.

A new NBC News/Marist poll shows the same result with Landrieu leading the primary, 44% to 36%, but losing a runoff 50% to 45%.
