From the bare bones quality of the requests, Bernie’s not living large. It would not surprise me if his team leaked the memo in order to stress his fairly spartan lifestyle.
I consider these requests as living large. How many regular people have assistants who go into their hotel rooms to set the temperature before they arrive or stock up on drinks and snacks? I'd say most voters don't have that luxury. Seems like an elitist prima donna thing.
Besides, it shows he's a hypocrite. He's for the Green New Deal yet wants his AC set to below 60 degrees and doesn't like low flow toilets. And the aforementioned setting of the thermostat before he arrives so that a room is cooling off with no one in it. Hypocrite.
