What in the world are you talking about? Politicians blackmailing each other for personal gain is unethical. And I'm pretty sure that "the electorate" doesn't qualify as a "governmental official".
"Is it not possible to profit by bribing/blackmailing a government official and benefit the public at the same time?"
The ethical content of an action is not determined by accidental effects. If I shoot a gun blindly into a street and accidentally save someone by shooting their attacker, that doesn't make my actions ethical. Bribing an official for information that you can then sell to the highest bidder is corruption. The intent matters.
"Please think these things through next time before you cathartically post that someone is "the enemy"."
I don't think that word means what you think it means.
