I don't know if Pence is a bad pick, but he has a deer in headlights quality about him under fire that has real Palin potential.— Noah Rothman (@NoahCRothman) July 15, 2016
Sarah Palin, who ran as VP in 2008 and has been a vocal supporter of Donald Trump, is not going to be speaking at the RNC next week. The reason? Apparently, it's because she can't see Cleveland from her house—the actual answer is that Cleveland is “a long ways away” from Alaska.
If there were not already ample evidence that Trump was tapping Pence as his running mate, I'd be suspicious that was the real reason. Barring that, she has to have been asked not to come by Trump, the only other reasonable explanation.
