Not just 'conservatives. There are a few 'liberals'/dems who are/were apparently unhappy with him with his most recent term. I get an eyeful of the dreck posted on my FB on an almost daily basis.
No president is perfect. I like Obama and nothing will change my mind there. Never a fan of Reagan (he denied AIDS for so long...) or Bush but both do have their finer points... in there... somewhere. And I know Obama has has his own missteps too.
I'm not saying anything about Trump.. I can't...but if something does threaten MY ability to life or my rights then yes I'm gonna figure out a way to fight tooth and nail. Yes I question his VP pick and cabinet picks and don't really think being a CEO or "businessman" really equates well to being a president without ever having had any kind of political office prior to it. That's my view. Others will have theirs and I respect that.
