I have a dream... where politicians have to at least be very _clever_ in their lies. Where "joe sixpack" is made aware of political lies swiftly, deftly, and with a minimum of bias. I know there are groups that do this--but they don't have nearly the funding they need to actually change the political climate. Only people who _want_ to know will find them, let alone keep up with them. Politicians seem perfectly free to ignore them and lie indiscriminately.
What if there were a "politics tax"--where every dollar spent on political ads had to be matched (by some reasonable percentage, but my desire would be 1:1) by funds for a political watchdog committee--which would then buy up ads to rebut (in an independent manner) the blatant lies. ((much like how it works for tobacco companies, yes? Who else has to do this?))
