I just called a local liquor store who advertises on Sinclair; its a great store with excellent deals on imported (yes, French) wines ... but what is really interesting is that the manager, who is a Kerry donor, told me his advertising is handled by a company called On-Target Media.
He told me he uses them only because they send out coupons for very little money; he didn't even know that his ads run on Sinclair.
I have yet to find a local # for them, but it makes clear that we can make some progress here if we find out which media companies are doing the buying and then let them know their customers will be hurt due to their affiliation with Sinclair.
