I personally think that the Senate won't find Trump guilty of anything. Republican support is beginning to climb back up for Trump and he'll most likely be able to get his allies in the Senate to say that the country must move on and allow healing to occur. That's the angle I see people using with the most success.
It may depend on whether Trump will sit at Mar-a-Lago with a KFC bucket and cry quietly about the lost Twitter account, or find some other outlet for his grievances. Himself he might be too lazy to actually do something about it but I'd be shocked if there isn't some enterprising grifter in his surroundings who could exploit his popularity, at least for a short-term profit (donations etc). Maybe Bannon can help him out now that he's been pardoned.
