Interesting probability problem

Everyone says 'jaago' and vote do... but if i don't know who is the right candidate... or is there a right candidate even?? So what will be BETTER? if i DO vote randomly i could vote for the right person if there is a right person or i could vote for a wrong person unknowingly and the right person could be affected... or i DON'T vote so if there is a right candidate he wont get a vote... and if there are no right candidates it wont make a difference either way...
