Sibling Rivalry

The Man on the Couch and I faithfully have watched the entire season of "Nashville Star," and both are anticipating that the sibling rivalry factor between the Hackers is going to push David St. Romain out of the picture.
As a country girl, I am convinced that they all will have successful careers whether they win or lose, but this season is different from previous competitions. All three of the finalists -- Angela, Zac, and David -- have heart, soul, and most importantly a voice.
All along, I've been rooting for Angela, and to be honest was ready to boot her brother out of the picture after the first week. But I've had a change of heart and ever since Zac sung his original song, I've been rooting for him to make it big.
More importantly, I want to hear who your favorite is.
Also, if anyone has plans to attend a stop on the "Nashville Star" concert tour, I'd love to hear about it -- or be stashed in your suitcase.
