yes, but that can be done by pc anyway (with a higher chance)... and not sneaky at all.
How can you say "higher chance" than a feature which doesn't even exist yet and which's success rate is therefore unknown?
There could also be a sneaky factor, in which random nobles would get "your scribes inform you that X tried to bribe them to have your vote changed in his favor". That person could then be able to blackmail the one who tried to rig the elections.
