Why do Dancing With the Stars viewers insist on casting their votes based solely on who they like and totally ignoring ability?

I get that people like Wayne Newton, but it's ridiculous that he stayed on despite a 15/30 from the judges, and Albert Reed was sent home instead.

Either the stars need to be of the same level of popularity, or, as one of my blog readers noted, the viewer vote should count for less. We don't need another Master P (or Billy Ray Cyrus or George Hamilton or Jerry Springer).
