I am not supporting anyone in the primaries, because I don't like any of them anymore, but I will vote for the nominee just to stop a Dem victory. Until recently, my tag line was Freddie T is the one for me!
It is ok to support no one, but in doing so, you should not make any comments biased for or against any of them either, unless you plan on balancing the load.
BTW that is impossible to do.
