Putting the backroom deals right out in the open and completely ignoring the will of the people, coupled with procedural shenanigans are far more chilling issues to contemplate.
A horribly-corrupt Republic may have some shady things going on, but they will be in the shade.

Putting in slightly-worse candidates may be a bit of "poison," but if that's the only way to remove a cancerous incumbent, it still needs to be done.
