Question

People present themselves for election by the public. It is to be expected that people will look into both their virtues and their shortcomings. Sometimes this is a kind of real benefit, to know with whom and with what we are dealing,
and sometimes it is gossip.
Is it reasonable that all the laws of malicious speech become more flexible for someone who puts himself up for election to a position, on the understanding that people will dig, investigate, gossip, etc.?
And in essence, has he waived in advance the standing that every Jew is entitled to under "judge your fellow fairly," and so on?
 
And likewise, regarding giving someone a nickname:
a name for a politician that has already become widespread?
A name that illustrates his virtues or his shortcomings?
 
After all, you need to know who he is and what he is like.
