They really should change the types of campaign paraphernalia allowed so that it's easier to remove and clean them up after the elections. Adhesive-types should be used less because of the hardship involved in scraping them off walls. Now that everyone's trying to be eco-conscious, there should also be a campaign-related legislation that mandates candidates to recycle their own campaign trash into usable products.
And now that the election process is automated, will the use of security cameras be far behind? Maybe if the budget allows.
