This article characterizes the new R senators as belonging more to the establishment wing of the party, in part because the party was fairly successful in getting its preferred candidates through the primaries, avoiding some of the surprises that characterized 2010/2012: http://www.nytimes.com/2014/11/16/us/new-senators-tilt-gop-b...

Some do have more track record in that regard than others though, so it might be that they won't all side with the national-security conservatives.

4 were swept into the House in the wave that brought the R majority and their voting record isn't exactly all happy happy with the establishment. Joni Ernst is not establishment. I am not sure about the other 2.

There were a lot a jockeying and some losses from the outsiders, but remember that Cantor got beat in the primary.
