With the Louisiana Senate runoff election favoring GOP Rep. Bill Cassidy, the Republican National Committee decided to use the campaign to begin refining and testing its voter turnout operation ahead of the 2016 presidential contest.

In a memo shared with the Washington Examiner, the RNC outlined its work during the month-long runoff campaign that public opinion polls project as an easy Cassidy victory over incumbent Democratic Sen. Mary Landrieu. The national party invested $2 million in the race, paying the same attention to early voting and get-out-the-vote activities that helped Republicans capture close Senate seats in the Nov. 4 general election.
