You will not see this on either side of the aisle because those are the majority of the voting population.
If either party were serious about doing what is in the best interest of the country, there would be no need for attack ads, political grandstanding or Rovian tactics.
Both parties would be able to sit at a table and discuss an issue in a civilized manner; making their case as bluntly yet respectfully as possible while listening to the other side and then trying to find a common ground that will benefit the majority but leaving both the far left and far right pissed off.
Don't expect to see that anytime in our lifetime anymore though.
