What should I do if my advisor is forcing me to vote on a specific candidate in IEEE elections? The IEEE holds yearly elections for senior positions in its societies. Every member of the IEEE has the right to vote in these elections, including me. My advisor, however, has candidates who, for one reason or the other, he supports and wants to get elected.

The issue is that he is forcing all of his students to vote for his candidates. Voting is done online. He even asks his Assistant Professor to personally stand next to the students and watch them vote on the specified candidates.

This makes me extremely uncomfortable, as I find it morally incorrect. However, my professor is in a position of power over the students and I am afraid of standing against him and losing my graduate course and scholarship.

Has anyone gone through something similar? What should I do?
Allow me to hypothesize a different tack from most of the other answers: Simply don't engage in this issue at all. As my mentor said once, "You constantly get institutional demands for some action, in some cases it's best to ignore them, and you'll find that many just go away." 

This request is so incredibly unethical, and also so completely orthogonal to your responsibilities as a graduate student, that it's hard for me to imagine your advisor spending time on tracking you down and taking revenge over it. If you think you might receive more pressure later on (e.g., I've sadly cracked under such circumstances), go ahead and cast the online vote in the privacy of your own home, and then later on say, "Oh sorry, I got a notification and cast the vote immediately." 

The request is so inflammatory that I don't see any use to "politely having an open discussion with your advisor". I think that only opens the door for defensiveness and retaliation. As wildly unacceptable as it is, I don't see it as being a good use of your time tracking down where to lodge a complaint over this matter (which your advisor seems canny enough to avoid documenting except verbally, so it would be just your word against his, according to comments above). 

At least consider the null action as a possibility.
