If this poll is at all accurate (and it might not because it's also a major outlier in the Senate primary), RIP conservative movement. A Trump win in Indiana would be the worst day in America in years.
You make an interesting point about why it might be an outlier. The WHTR/Howey IN poll early this week showing Trump over Cruz by 6, showed Young over Stutzman in the IN GOP U.S. Senate primary by 12. Well, this NBC/WSJ poll showing Trump over Cruz by 15 shows Young over Stutzman by
32! That's a 20 point greater lead by Young than in the other poll in the same week. That seems....unlikely.
