Rove's Insane Ravings

Karl Rove is claiming that Hillary Clinton has permanent brain damage!  Note that when it was first announced that Hillary Clinton had a fall that caused temporary brain damage, the Republicans accused her of faking it.
 
So, how will we know if Hillary Clinton has brain damage? Decades ago,  toward the end of Ronald Reagan's first term in office, I entered the place where I was working and asked one of my colleagues how he was doing.  "Not so well," he responded, "my father has Alzheimer's." 

"Well, maybe he should run for the presidency." I suggested, "After all, Reagan made it."  That raises another question:  "If, indeed, Mrs. Clinton has
brain damage, shouldn't the Republicans find her as desirable a candidate as they found Reagan?"
 
So how will we know if Mrs. Clinton has permanent brain damage?  If she, like Ronald Reagan, switches parties, that should be a pretty clear indication that Rove is right.
