Question re: Ohio Dem Party mailings

I'm a newbie to the local political scene, so I haven't inherited the scorecard. One thing that disturbed me was the number of anti-Bell mailings I got leading up to the election. The thick, glossy postcards were not in favor of another candidate, they were just anti-Bell. When we got our 7th such postcard, we went downtown and picked up a few Bell signs for the yard!

My question is, how much money was spent on this mailing campaign? Do I have the right to know, or is this proprietary information? And how can I let the committee know that this tactic, in particular, backfired on them? Especially since we got enough campaign signs to share with neighbors who otherwise would not have driven to Bell HQ.
