It is an easier case to make that Cruz is for Cruz, than that Cruz is for GOPe.
If Cruz were a phoney conservative like Tom DeLay or Ralph Reed, then why is he running for President? Why doesn't he stay put, like DeLay did, in his safe congressional seat?
Maybe this is just an elaborate way for him to get money from rubes, but it is money for Cruz, and not money for the GOPe.
In the end it might turn out that Cruz is the reason why the GOPe candidate Rubio doesn't outperform Trump.
Imagine that: a candidate like Cruz who is 90% behind the Tea Party line prevents GOPe Rubio from getting ahead of Trump.
How ironic.
Ted has a lot of, well, let's say "billable hours" invested at this point. If the GOPe offers a settlement, he'll declare victory, tell his "clients" how wonderful it is that the GOPe is starting to come around, and work hard to rationalize whatever Rubio has to say on any topic.
Looks like a GOP establishment insider to me:

1996: Law clerk to William Rehnquist, Supreme Court
1997-1998: Private law practice, worked on impeachment of Bill Clinton, served as private council for John Boehner

2008-2013: Private law practice, represented such corporate clients such as Pfizer, a Chinese tire company, B. Braun Medical Company, Toyota, some major personal injury cases.

Ted Cruz belongs on the US Supreme Court, not in the White House.
