I am not convinced of this. Anakin in 19 BBY is at the height of his powers and Palpatine has just barely survived a fight with Mace. Palpatine's got a shot, but I wouldn't call it a sure thing.
This makes sense if we ignore that in the arc immediately preceding the Jedi discovering Dooku's hand in the construction of the clone army, a clone went into a fugue state and executed a Jedi, and it was blamed on a "malfunction with his inhibitor chip".
I feel like Clone Wars probably needed to choose between the Sifo-Dyas episode and the Clone Conspiracy arc, because doing both literally back to back makes the Jedi look like complete fools.
