Final answer:
A cartoonist in favor of Radical Reconstruction would likely not support Andrew Johnson, given his lenient approach to rebuilding the South and disagreements with the Radical Republican's transformative agenda.
Step-by-step explanation:
Understanding the differences between Andrew Johnson and the Radical Republicans can give us insights into who a political cartoonist might favor in the context of Radical Reconstruction. Initially, President Johnson appeared to be in line with the Radical Republicans, believing that the South should be punished for secession and showing hostility towards Southern aristocrats. However, Johnson's position shifted when he assumed the presidency, and he sought to quickly reincorporate the South into the Union on lenient terms, diverging from the Radical Republicans' intent to fundamentally transform Southern society and ensure constitutional equality for freedmen.
Given this background, it is likely that a cartoonist in favor of Radical Reconstruction would not be supportive of Johnson's approach. Rather, the artist would be more aligned with the Radical Republican agenda which pushed for a hardline transformation of the South, including suffrage for black men, dismantling the plantation system, and enforcing changes via military districts as outlined in the First Reconstruction Act of March 1867.
