Of course you want your guy/gal to win! Cheering for him/her is normal. Some supporters cheer if an opponent is suffering from health issues that could be dangerous/life-threatening. How is that OK?

I didn't cheer when saddamn was hanged but I understand why people did.

If hillary must drop out of the race it will be a better thing for millions and millions of people so maybe that is to be cheered for. I will still not cheer but I understand it.
