Her game plan is to either position herself for VP or Sec of State. If you look at the first four primary/caucus states...other than New Hampshire, she has zero chance in the other three primaries. I think her money will dry up by that point, and she will exit the stage.
She might also be vying for more of an inside position, like Howard Dean. Where she can still make a ton of bucks, but without as much risk in getting those dollars.
You are right.
Running in the primary is a stepping stone to a cabinet post or the VP slot.
I mean, Biden's cadre doesn't like her, doesn't trust her ... Not even for Squaw of Commerce ... Maybe an Ambassadorship to Assateague Island where she can hang out with all the other wild horse faces...
