Democratic candidate for Ohio's 15th congressional district, 
Mary Jo Kilroy, had a well-place campaign ad right in the middle of Saturday evening's Olympic coverage.  It was positive, highlighted her successes as a Franklin County Commissioner, and explained her goals if elected to Congress.  I thought it was great.  
Kilroy's ad did not mention the name of the Republican opponent who is a corporate bank lobbyist and recipient of money from big oil.
