Grant and Lincoln's invitation

[L Verge]

I have absolutely nothing to back this up, but I have never felt that Booth had any plans on assassinating Gen. Grant. I have always thought that just the three that we know were the intended targets because of their power and position that could bring down the government if they were destroyed. It didn't help Seward any that his rabid abolitionist views and his quotes about his power "to ring a bell and send people to prison" (not the exact quote) didn't sit well with folks like Booth.

I think Booth probably saw Grant as a puppet of the evil government in Washington - just doing his duty. And, at this point in the game, there were other generals who would jump in to fill Grant's boots if he were killed, so don't waste the effort and the bullet.
