It only works with those who can be easily distracted into going sniffing off the trail (valid issues) as soon as the red herrings (irrelevancies) are dragged across it.
Knee-jerks who are in the habit of "reacting" to whatever they see and hear, either haven't developed critical thinking skills, or they allow their emotions to overrule their heads. It isn't possible to save such people from themselves.
Until they grow up, the only political party they will be emotionally able to relate to is the RAT Party.
