Big difference
"Trump has made great play over rival Hillary Clinton’s use of an insecure personal email server"
There is a BIG difference between Hillary ordering her people to set up an insecure, exposed to the internet server to house Top Secret and above materials (to avoid the "hassle" of dealing with state department device regulations) and a technician not applying a recently released patch on a webserver.
Having said that, it's totally uncool that this happened but Trump didn't tell his IT guy "Ok, go expose our donor base". Hillary definitely said "go set up something illegal, and then shred it if we're caught".
Huge difference. I hope you Brits understand the power grab going on over here right now. If Hillary wins, you'll never get those "refugees" out of your country. At least if we get Trump in office you guys can tell your leaders "hey, America's not doing this, why the hell are we?"
