There have been many designated 'hatchet men' in politics, one notable one was Bob Dole. He was the guy who had to go out and tear down anything the opposition was promoting.
Problem is, the hatchet man rarely get to shed the role and become top dog. (See Bob Dole tank in his presidential bid.)
Ikki Nikki is now the RINO hatchet man (person, woman, girl, idiot, whatever) and she seemingly thinks tearing down Trump is going to help her position. Highly unlikely.
Trump serves as his own hatchet man, but he has the personality (unlike bland Bob Dole) to pull it off. Nikki lacks the personality to pull off a primary win, let alone a general election.
Of course, they add the senile old man defense when it suits them.
Proof enough to 25th the old guy - the special prosecutor finds him incapable of aiding in his own defense at trial.
I, for one, expected this after Joe was already out of office.
