Following up on Nate, this wouldn’t be a shocking polling error in Indiana. Right now, Sanders is holding a 4 percentage point lead in Indiana. Yes, none of the pre-election polls had Sanders winning. And yes, the average of polls taken over the past three weeks had Clinton up by a little over 7 percentage points in Indiana. But before the Wisconsin primary, I calculated that a poll before a caucus or primary had an average error of 11 percentage points. In other words, right in line with the error there appears to be in Indiana right now.
