He's trying hard to set things up which will keep going after he's gone. Certainly if Hillary wins.
That he's spending the time, indicates that he thinks Trump will lose -- by whatever means necessary.
With much of the GOPe leadership, including Ryan, working against him, it is going to be really hard for Trump to overcome them all. He is being forced to almost go third party even under the GOP banner. And I share your fear that if despite all the opposition, Trump looks like he will win, the uniparty might do even more to make sure they win. After all, it is the future of Western civilization and untold trillions of dollars at stake.
