Congress Daily (at National Journal wrote this about the IL-03 race:
Now, Lipinski faces John Kelly (D), who “blanketed the district with” 5 “direct mail pieces focusing on” Lipinski’s ’04 election
They also wrote that Kelly raised $78,000—-he actually raised about $43,000 including $15,000 he loaned to his campaign.
It’s unclear given that he spent $15,000 on mail that he could have had 5 blanket mailings. It’s pretty unlikely he could afford it since if properly done, he’d report about $7,000 on hand at the end of the pre-primary.
