U.S. Sen. Mary Landrieu is courting young voters in several appearances across Louisiana this week, talking about her support for legislation that could lower students’ college costs.

The Democratic incumbent, locked in a tight race for re-election, is making stops at colleges in Baton Rouge, New Orleans and Shreveport. On Wednesday, she was speaking at Dillard University.

She’s describing her work on bills that would drop student loan interest rates and increase Pell Grant awards.

Most importantly, she’s urging the typically low-turnout group to vote Nov. 4.

Considered vulnerable, Landrieu is looking for new voters who could make the difference in her tough bid for a fourth term. Her main Republican challengers are U.S. Rep. Bill Cassidy and retired Air Force Col. Rob Maness, a tea party favorite.
