Caveat: I got it wrong, too. I said that it was much more likely that Donald Trump would either win big, or lose big, than it would be for him to get into second or third place. Guess what happened?
So I can’t really criticize the pollsters too badly. Of the possible reasons listed here as to why the polls were off, I’m going to go with ‘organization.’ Ted Cruz and Marco Rubio had people who not only looked over what the Democrats did in 2008 and 2012; those people also took copious notes. Donald Trump’s campaign… did not. Which is one of the things that maybe Trump should be wanting to fix today. And I mean literally today. It would take a crazy amount of money to set up a working GOTV/voter identification system by the weekend using off-the-shelf components, but the man’s a billionaire, right?
PS: Actually, yeah, I’m being serious. What’s the point of having a billion dollars if you don’t use it to solve problems that only a billion dollars could solve?
