This is precisely the effect of having a two party system. Negative campaign ads help you as much as they hurt the other guy - Negative campaign ads are also a more effective way to spend your money. Thus we've seen extreme polarization in politics as parties have stopped needing to say what they'll do - and started fear mongering about what the other guys will do.
