NEW ALBANY, Ind. (AP) — Indiana Senate candidates Richard Mourdock and Joe Donnelly have kept up their attacks on each other in their final debate before Election Day.

Republican Mourdock used his opening statement in the debate Tuesday night to criticize Donnelly for claiming to be a fiscal conservative after voting for the federal health care law that will expand Medicaid rolls if it stands.

Democrat Donnelly jabbed Mourdock for his partisan stances. Donnelly says he'll be a strong independent voice who will support all Hoosiers like Sen. Richard Lugar and former Sen. Evan Bayh have.

Libertarian nominee Andrew Horning joined them for the debate at Indiana University-Southeast in New Albany.

Auto workers supporting Donnelly and tea partiers backing Mourdock held rival demonstrations outside the debate amid a large police presence.
