Ted Cruz is starting to win the "somewhat conservative" in Iowa

In the latest Quinnipiac poll of Iowa voters, Trump has a slim lead and is statistically tied with Ted Cruz.  What I found most interesting was that Cruzs' improvement from the last poll came mainly from "somewhat conservative" voters where he went from 17% last time (statistically tied for third) to 25% now (statistically tied for first).  His support among the very conservative and moderates increased only a little between the two polls.  Looks like Ted Cruz is doing what he needs to do and is broadening his appeal.
