This afternoon, you may have seen a story that seems to say that Donald Trump has dropped 9 points in New Hampshire since Iowa. It's based on a Public Policy Polling infographic that seems to demonstrate a drastic drop in Donald-related interest, but it doesn't tell the whole story.
The first poll was taken among people who self-identified as Republican. The second, lower poll, was taken among people who are routine caucus-goers. The number is lower, yes, but not for the reasons stated, though it does still demonstrate a systemic problem with Trump's campaign - the problem he and others probably feared: that fervor over his candidacy doesn't necessarily translate into votes.
Trump seems to have gotten the message in New Hampshire, but does he have enough time to successfully change course?
