That depends on the issue. Johnson did not became a martyr, and him until the time of TR and Wilson, the office of President was reduced to the Whig concept of it.
OweBowMao is the issue.
He will be martyred if you look at him cross-eyed, because he is the first Black president after Clinton.
The minute he is impeached, the media will demand he be chiseled onto Mt. Rushmore. We live in different times from the days of Andrew Johnson when at least reason prevailed.
I just want him to sink into utter insignificance and total disrepute. I want his name cursed under every breath for what he has done to this country. I want him to feel the shame and dishonor to which he is entitled.
