Answer:
Reasons for irrational behaviour : Political brand name establishment in favour of candidate, enhancing brand loyalty towards.
More knowledgable public : Would value candidate working on real development, rather than mere brand name.
Explanation:
Political elections are determined by the public's impressions of the candidates rather than the candidates' views on the issues.
Reason(s) of such irrational voting behaviour could be : The candidate having established a personal brand image of himself/ herself, specially in a particular community group. This makes the people of the community being 'brand loyal' towards their candidate, irrespective of his or her ideologies. It is also possible to make that political personality (candidate) an important part of 'national image' or 'community leader image', which reinforce support for the candidate, irrespective of person perception and attitudes.
If public were more knowledgeable about factors that affect person perception and attitudes : The political support would not be based on lineaged political brand names. It would rather be earned on the basis of candidate's performance for socio - economic, political upliftment. This would give power in the hands of deserving politicians & create a message that 'real work' & not just 'name' is needed to gain political success
