Well, she’s gotten a lot of mileage out of her “concussion”. Because of that episode, she gets away with confusion about facts.
I’m of the opinion the coughing fit is one of convenience that was thought up and perpetuated by clinton herself, along with bubba.
Now that it’s creating the attention she meant for it to do, she laughingly waves off any reason for concern and giddily denies any health issue.
Then when she needs a rescue from having to answer a question...here comes the coughing fit that by now everyone is familiar with, and accepts as real and not a ploy for avoidance.
Then all anyone has to do is observe that the stress of having to think on her feet sends her into a coughing fit. And then raise the question of whether it is a good idea to have a president who becomes physically debilitated every time a stressful situation comes up.
