Yes, I agree, that's their plan - king of the hill on all counts. And whereas I can't see any way to stop The Twisted One from becoming SG, I don't actually think Ol' Table Legs can make it to POTUS... Billy-boy has the charisma - not her - and that is what's needed to gain POTUS status in the US...
You needn't be terribly bright, terribly experienced or have any morals whatsoever to become POTUS.. you just need to be reasonably good looking, have bags of charisma that shows up well on TV, be able to deliver the quick retort in a debate and to be able to pick sly folks to keep watch and guide you along the way (and where needed perform a timely dirty trick or two). Sad but true. Fortunately, Ol' Table Legs has absolutely NO charisma, so I can't see her making it. (Nevermind the fact that she looks like a mud fence in a rainstorm.)
