Did Booth want Johnson to be president?

Jerry, if this conversation be true, then I think there is a good argument that Booth's goal was to create chaos in the Union government, and Johnson's death was a part of that.

Agreed. What I'm saying is that when it became obvious to Booth that his Plan A became unfeasible, due to Atzerodt's refusal, his Plan B was to let Johnson live rather than send Powell after him. Why?

With Johnson alive the death of Seward meant nothing if mass confusion was his goal. I'm speculating that removing Lincoln and putting the Southerner, a man Booth knew into power, was the outcome he consciously chose.
