I was at Norfolk's Janaf branch library today. Posted on the front door as you entered: a notice for a "Norfolk for Obama Organizational Rally" tomorrow.
Okay, if there's a community bulletin board, you might be able to make a case for it there. However, this was on the front door where everyone entering the library would see it. The obvious point was to push Barack Obama's candidacy.
A taxpayer-funded service shouldn't be used that way.
