Humble, you’re being a bit daft on this one.
The poster wants Mitt to quit the race (if he’s not going to burn ObamaTax to the ground and salt the earth afterwards).
If Mitt were to read his post and quit the race (!) the convention would decide who the new GOP candidate would be.
Gee, let's see. Mitt just spent five years and millions of dollars - including a fair chunk of his own coin - winnning the nomination. Do you seriously think he would, barring an incredible scandal or serious illness, walk away from it now?
I think not.
