Bill Cassidy Defeats Mary Landrieu to Become Louisiana's Next Senator-thetimespicayune: Republican Rep. Bill Cassidy notched a commanding victory over Democratic Sen. Mary Landrieu in a Dec. 5 runoff, capturing 56 percent of the vote over the three-term incumbent and ousting the chamber's last remaining Democrat from the Deep South. In keeping with his practice during the campaign, Cassidy has focused his post-election remarks on plans to disrupt the president's agenda, rather than outlining his vision for a GOP-controlled Congress.
