Following on the heels of the well-received and sometimes-uncomfortable “Primary Questions,” series on the CBS Evening News, Katie Couric is back with a similar series — “Presidential Questions.”

The series debuts on Wednesday night. As in “Primary Questions,” the same set of questions is asked of each candidate, with one question airing each segment of the series. So far Sen. John McCain has been interviewed, and Sen. Barack Obama‘s interview is set for tomorrow.

“Presidential Questions” runs every Wednesday until Election Day.
