Campaigns: controversies vs. performance, propaganda vs. facts

I think political campaigns must consciously gravitate towards performance and facts. I have noticed an alarming trend wherein being controversial is becoming the path to being elected, and astute propaganda is the vehicle for effective campaign. Both of these are not really the essentials for public service. I wish campaigns are more anchored on actual performance and facts. Otherwise, it will not be an electoral  victory for the people but for professional hecklers and propagandists instead.
