CNN and WMUR have published the latest New Hampshire poll under the "Trump on top, battle for second emerges."

But here's the thing about the poll: the sample is tiny and unreliable. Most of the poll was conducted before the Iowa Caucuses. The two days that were conducted after the caucuses had this sample: "209 respondents who say they plan to vote in the Republican presidential primary."

So that is a miniscule sample size, resulting in a margin of error greater than 6 percent. And it's not even a poll of likely voters.

In short, this poll doesn't tell us anything about New Hampshire voters post-Iowa.
