The main issue is whether or not you believe that's business as usual. And it might be, I'm not discounting that.
Having lost patience is a function of applying heuristics to the never-ending, time-consuming task of evaluating information. I'd say open-mindedness refers more to an outlook, a goal or an attitude. They're not mutually exclusive. I get that the language is imprecise.
A person who simply dismissed every incoming datum which fell into the "This Clinton scandal will totally blow your mind!" category would have been right very close to 100% of the time, which is a pretty good heuristic. If need be, that same person can simply wait for the evidence to mount and then alter their opinion.
I have pity for anyone who really feels obligated to separate the wheat from the chaff (in the interest of open-mindedness!) when it comes to every outraged Clinton news item.
In fairness to "people," a perfectly open minded person could have lost patience with "This Clinton scandal will totally blow your mind!" way back in the nineties. If you've been carefully parsing the soundness of every manufactured Clinton scandal since the early nineties, I feel for you.
