I completely disagree. You don't need a scientist to take over a politician's body, just some normal, reasonably-intelligent person who's willing to listen to others and isn't evil or corrupt. The problem is that politicians tend to be sociopaths, who as a group comprise probably about 5% of the entire population. The stupid ones go to jail, but the smart ones become politicians, CEOs, etc., because they can outcompete regular people since they don't have a conscience to hinder them. So if you replace their brains with those of non-sociopathic people (the other 95% of the population), things should improve.
