(Full disclosure, this is the only way I'd ever watch either show:)
You are correct, that is how they get viewers. However, DWTS promotes using noted personalities while American Idol promotes the “finding the needle in the haystack” singer from random candidates.
Claudia’s “audition” and golden ticket, was neither random, not based on her talent. As I said, she’s an OK singer, but definitely not in the same league of so many other, actual random candidates.
