The Indiana Senate race continues to be a tight battle, with a slim edge for Democratic Rep. Joe Donnelly over Republican state Treasurer Richard Mourdock.
Donnelly leads 40 percent to 38 percent, plus 7 percent for Libertarian candidate Andrew Horning, in a Howey/DePauw poll released Thursday. The survey of 800 likely voters was conducted Sept. 19-23, and has a 3.5 percent margin of error.
The same poll shows Mitt Romney leading President Obama, 52 percent to 40 percent. However, Mourdock appears to be having a hard time sealing the votes of people who had supported longtime GOP Sen. Dick Lugar, whom Mourdock defeated in the primary.
