The more I think about this, the more perfect it is. Both had stellar track records in the minors, numbers that suggested they were about to be the next big thing. Both got their cup of coffee, did what they were expected to, and looked primed for superstardom. The establishment had anointed them, and everyone agreed they would be stars. Ackley was destined to be a squeaky clean Pete Rose, and Hillary was on her way to something almost as impressive.
But then, disaster struck. For Dustin Ackley, it was the Lefty Strike Zone (TM). Pitch after pitch sailed three inches outside, and the umpire barked "Steee-Rike". Dustin grimaced and muttered "that's a ball." Then he, reset, and tried again. And again. And again.
Some years later, Hillary underwent the same process. Tweet after tweet came sailing by, three standard deviations of political correctness outside the norm, and she watched each one sail past with cool indifference. When asked why she never offered at them, she smiled (Hillary Clinton's smile is basically a grimace) and said "Those tweets are low and outside. When they go low away, I look high and inside." She kept stalking her pitch. She never got it.
Hillary and Dustin stayed the course, and watched tweet after tweet, pitch after pitch go by them. They struck out, over and over. Gradually the fans became disenchanted with their respective franchise players. It's just hard to believe someone who says they aspire to be great and win a championship, but makes such little effort to adapt to the world around them. There is a sickening arrogance in someone who can strike out looking three times in a night, then grumble in the post-game interview "Those pitches were just deplorable. I can't work with that at all." Time passed. Disenchantment became disgust, then hate. Careers died. Now both are just footnotes to history.
Seriously, the only way I could like this analogy better is if Hillary gets a bizarre haircut and then gets traded to the Russians.
