Democrats plan to use a student loan bill introduced Tuesday by Sen. Elizabeth Warren (D-Mass.) as a wedge issue in the 2014 midterm elections, forcing Republican candidates to either support it or explain why they don't. Dem strategists think Warren's legislation—which would lower interest rates on most federal student loans below 4 percent, reducing millions of Americans' bills by hundreds or thousands of dollars a year—could help turn out young people, who tend to vote for Democrats. Fifty-seven percent of Americans ages 18 to 24 say student loan debt is a "major" issue for them, according to a recent Harvard poll.
