Mourdock more confident than Lugar heading into debate

"I'm really looking forward to it — the high point of politics is when you can stand up at a microphone and inflict your opinions on on someone else," he told The Hill earlier this week. "The last 30 days [of the primary] will be about demonstrating to the voters you're capable of doing the job, and I feel that after the debate they’ll say Mourdock stood toe-to-toe and defined himself against Senator Lugar... This is giving us a chance of letting people know who the heck we are."

Mourdock admitted public speaking isn't his forte, but argued that he's improved as the campaign has gone along.

"When you get in the business of politics, you've got to do things you're not necessarily comfortable in doing," he said. "Hopefully I am better every time I go to the microphone, and I do that two to three times a day."

Mourdock is running to Lugar's right and has shown some signs of momentum — a recent nonpartisan poll had Lugar leading him by a narrow 42 percent to 35 percent. While the debate won't be watched by many voters, how it is covered could affect the race, and if either candidate makes a mistake it is likely to resurface in attack ads.
