I think very highly of Rand still. If he says he’d filibuster Bolton, believe it.
I hope that Trump, if he is going to pick Bolton, brings Rand in for a sit down before he announces to hear his concerns and tries to work some differences out.
No need to make an enemy of a very vocal and savvy senator.
Rand knows and understands Constitutional principles well. He holds a very strong dislike of Bolton because he sees him as the a most aggressive war monger. So his differences are ideological. He is going to be hard to quiet, but I’m sure DJT will do his best, if Bolton is his choice.
It will be very sad to see him filibuster though, because the Dems will jump onto and exploit this exponentially.
Time will tell, although I hope he picks Rohrabacher. Paul should like him well enough, I would hope.
