Gosh I hate it when politicians are useless and incompetent, since it just validates the false populist propaganda that politicians can be useless and incompetent, which is clearly not true (even in cases when politicians actually are useless and incompetent, which they of course cannot be, since that is evil propaganda).
Politicians can be quite evil, but in a functioning democracy they need to be at least competent at gathering support and navigating the occasional backstabbing plots to make it to the highest ranks of government. So I'm hesitant to call them totally incompetent.
