if Palpatine was really that smart he would have used his own clone for the republic's army instead of Jango Fett. Why the hell did he use Jango anyway
well, if you count up the total posts it may be 50%
but "what i type" implies the total words typed, and since i type waaaay more when i'm being serious, you are incorrect. my jokes are usually 1 liners...so you could say that a very low percentage of what i type is joking.
The question is: How far back does Sidious's plan go? The Answer:
Palpatine made his way into Naboo politics in the beginning of his mid-life, then made his way to Coruscant as an elected representative. As time went by, he continued to manipulate people until he was elected Supreme Chancellor, then made himself Emperor. It was a simple plan, and every politician does the same thing. The only difference is that Palpy wears a black hat while doing it.
From the beginning of all of this, he had been a Sith Lord. His plan began when he was a young man, which was not 800 years ago. He is a regular human being, and his normality is what made him want to control the galaxy. His plan goes back only a few decade before TPM. There is nothing more to it.
If you don't like that, and would rather think of the situation as being as massive conspiracy of Sith ghosts and stuff, then you are neglecting the psychology of how evil is born.
