Putting Harry into political power was certainly part of the original plan (spelled out by Quirrel in parseltongue, even), although I'm not sure if the rest of the original plan was "make Harry do all the work" (in which case why constantly try to make him less altruistic?) or "possess Harry and enjoy that power".

I'd assume the new plan must revolve more around "stop Harry from ripping apart the stars and ending the world", and indeed Voldemort confirms "all I have done, iss to ssmassh that desstiny at every point of intervention". But you'd think the new plan wouldn't be "1. Make it possible to kill Harry. 2. Leave Harry with his wand and tell him not to interfere with next moves. 3. ???" it would be "1. Make it possible to kill Harry. 2. Kill Harry."

(Random aside: we have someone named "Jossed" coming up with theories about fan fiction? That's marvelous. Or possibly morfinous; I've heard a rational world wouldn't have conveniently-coincidental names.)
