So I didn’t hear back from you so I did a bit of research on my own. I was shocked to find your numbers were just a bit off or at least from what I found on Real Clear Politics.
There were 44 polls listed on the 7th and 8th of November 2016 and I’ll be darned if only 12 of them had Trump winning. That’s means 27% of the polls were right.
Of course, there were 194 polls listed in November of that year and you guessed it, 59 had Trump up. That’s 30% so I can see where you got confused.
Fact is, polls are skewed, easily manipulated, and used by the surrogates to get out the votes. But I’m sure you don’t believe that, it’s certainly an inconvenient truth.
