"Bullet voting."  The question has risen is this an acceptable practice.  I believe it is, and here's why.
So often we are given bad choices that we just don't want to vote for.  The ballot, in the State Senate race, says "Vote for not more than Two."  That means exactly that, you can not vote or vote for one or two.  Right there you are given permission to vote for only one candidate, "bullet voting."  Or, you can write in your 2nd choice if they are not on the ballot.  
Everyone is entitled to their opinion on this subject, but I believe you have the right to vote as you wish.
