Got through about half of this. The writer is telling a lot more about himself than he probably realizes. His mention of Joel Osteen is a clear indication that he works off his emotion, suspicion and a store of half baked impressions.
I assume you are referencing this…
"... because for all his obvious talent Cruz’s rhetorical style frankly makes my hair curl a little. Striking a pose that lands somewhere between the oleaginousness of a Joel Osteen and the self-assuredness of a midwestern vacuum-cleaner salesman, Cruz delivers his speeches as might a mass-market motivational speaker in an Atlantic City Convention Center." The comparisons are over the top, but I understand what his point is.
