For those of you who want to drag Coulter's support for Romney and Christie into this,
No one has to be consistently conservative, or any kind of modified conservative (such as "social conservative" or "fiscal conservative"), to understand that the Democrats will once again break their promise to close the border just as they have been doing since 1986. Arguments attacking Coulter for her support of Christie and then Romney are attempts to change subject and/or move the target.
The consistency (or inconsistency) of Coulter's conservatism is irrelevant. The article is about how the Democrats will never keep their end of the bargain, and how freshmen GOP Senator Rubio is a babe in the woods trying make a deal with a nest of snakes.
