I would save that title for the Clinton but, I wouldn't want to offend their supporters.
Once again you are implying that those who do not support Trump are Clinton supporters.
By virtue of supporting Trump his supporters have guaranteed that Clinton will, barring divine intervention or unforseen circumstance, be the next POTUS.
I would simply state that by doing so, you are the real Clinton supporters. You have set her up for victory.
If you don't like that characterization, quit equating nevertrump with pro-Hillary. Otherwise, you may see it a lot.
