Aside from delivering anti-Obama messages, these trolls also require to "register" i.e. give your email address and zip code so they can send you more of their tripe.
To counter that I came with the idea of listing Cheney's email address: Vice President Richard Cheney: vice_president at whitehouse.gov and White house zip code 20500. If enough people do the same and give these assholes email addresses of other right wing assholes, it would create some noise in their propaganda machine, not to mention harassing the right wing assholes by "verfication" messages from newsmax.com.
