Landrieu needs 30/30 strategy to defeat Cassidy

In the open primary Nov. 4, the Democratic turnout effort hit the first target: Black voters made up 30 percent of the electorate, based on exit polls, which is just shy of their share of all registered voters in Louisiana. And they gave Landrieu 94 percent of their votes, according to those polls, which provide a rough measure of voter behavior.

But Landrieu fell dismally short of the second goal: Only 18 percent of white voters supported her, the exit polls showed.
