"telling it like it is" is just coded language to say "he says the shitty things that I think are true, so it makes me feel less shitty and empty inside"
it is pretty powerful having your beliefs be broadcasted and repeated ad nauseum by a figure you consider of authority. like discovering the idea you thought you had originally being already out there said by someone you hold in respect. for trump followers him just being the nominee of their party of blind choice is already worthy of praise and admiration.
trump just loves their endless money pit, and will say just about anything to get it. they love that they have a former president with attention from the media to propagate their delusions.
