Chabot shouldn't be questioning why some people are drug tested, he should be questioning why anybody is drug tested. Presumably "George" is a good employer & hires qualified workers with good track records. Presumably he would suggest a medical intervention if one of his employees was slurring or staggering - indeed, the worker might have suffered a minor stroke. But, no Chabot wants employees, in a fairly un-American fashion, to prove their innocence.
The second caller is worried about new neighbors that might not be of the same caliber as her friends & fam. Chabot fairly butchers his explanation of block grants, but, again, offers no recommendation of liberty enhancing smaller government.
Negativity & big intrusive government ~ all Chabot has to offer.
