Anyone can “be manipulated.”
Nonetheless, the system of government we have relies on the will of the people, as expressed through their elected representatives. That’s how we do government since 1789. The attempt to “manipulate,” voters is otherwise described as advocating for voters to vote for your party. The complaint that voters are too stupid to make the correct choices – known also as “the choices you prefer,” – is not an argument for democracy. It’s an argument that you should get to be in charge, and not the stupid voters.
